Why Vertical Scrap Is the Most Reliable Strategy in TFT Set 13

The Scrap trait has returned to Teamfight Tactics in Set 13: Into the Arcane, bringing back one of the most intellectually rewarding and tactically flexible mechanics in the history of the game. At its core, Scrap revolves around resourcefulness—turning incomplete item components into full, functional items at the start of combat while shielding your entire team based on the sheer volume of components on your board.

In a meta often dominated by rigid "Best-in-Slot" (BiS) item requirements, Scrap offers a refreshing alternative. It rewards players who understand tempo, item distribution, and flexible positioning. If you are struggling to find a consistent top-four strategy, mastering the Scrap build is your ticket to climbing the ranks.

Understanding the Scrap Mechanic in Set 13

To play Scrap effectively, you must first understand the mathematics behind the trait. It is not just about having the champions on the board; it is about managing your bench and your units' inventory.

Item Conversion and Tiers

At the start of every combat phase, the Scrap trait takes uncombined components held by Scrap units and transforms them into temporary completed items for that round. The number of components converted depends on your trait tier:

2 Scrap: One component converts; the team gains a small shield.
4 Scrap: Three components convert; the team gains a significant shield.
6 Scrap: All components convert. Furthermore, every item on your board becomes "Lucky," meaning the RNG (Random Number Generator) for converted items is weighted toward items that actually benefit the unit holding them.
9 Scrap: This is the ultimate cap. All components convert, and you generate several Radiant Items, which are the most powerful artifacts in the game.

The Shield Value

The shield granted by Scrap is team-wide. It scales based on every single component on your board—this includes components that are already part of a completed item. For example, if you have five completed items (10 components) and two loose components, the total shield is calculated based on 12 components. This makes Scrap one of the most durable frontline traits in the mid-game, as your entire team—carries included—starts the fight with a massive HP buffer.

The Scrap Roster: From Early Game Stability to Late Game Dominance

The Scrap trait is spread across all gold costs, making it accessible at every stage of the game. Understanding the role of each unit is crucial for a successful build.

Powder (1-Cost: Scrap, Ambusher, Family)

Powder is your primary utility piece in the early game. Her Monkey Bomb deals area-of-effect (AoE) magic damage and, more importantly, applies Wound and Burn. This reduces enemy healing, which is vital in early-game skirmishes against Bruisers or units holding Bloodthirster.

Experience Tip: In our testing, giving Powder a single Tear of the Goddess is the most efficient play. The Scrap trait will turn it into a mana or AP item, allowing her to cast her debuff almost immediately.

Trundle (1-Cost: Scrap, Bruiser)

Trundle is the quintessential early-game tank. His ability to heal based on missing health makes him incredibly annoying to kill when backed by the Scrap shield. He bridges the gap to the late-game frontline perfectly. If you are playing a reroll variant, a 3-star Trundle with a single component like a Giant's Belt can solo-tank most Stage 3 boards.

Ziggs (2-Cost: Scrap, Dominator)

Ziggs provides consistent backline magic damage. While he usually falls off in Stage 4, he is an excellent item holder for your late-game AP carries like Ekko or Rumble. His ability to split into mini-bombs makes him great at finishing off low-health targets that your primary carry might have missed.

Gangplank (3-Cost: Scrap, Form Swapper, Pit Fighter)

Gangplank is the "bridge" unit. As a Form Swapper, he can adapt to your needs. If your frontline is weak, he can sit in the front; if you need more damage, he functions as a mid-range threat. His cleanse mechanic is particularly strong in Set 13, where crowd control is prevalent.

Corki (4-Cost: Scrap, Artillerist)

Corki is your primary physical damage carry. His missile barrage provides innate armor shred, which means you don't always need to build a Last Whisper. This frees up his item slots for raw damage like Infinity Edge or Giant Slayer.

The Scrap Strategy: We recommend always fully building two items on Corki and leaving the third slot open for a Scrap component. A Scrap-generated Guardbreaker or Deathblade can often be the difference between a win and a loss.

Ekko (4-Cost: Scrap, Ambusher, Firelight)

Ekko is the most versatile unit in the Scrap roster. He functions as a diver who shreds magic resistance and provides immense backline pressure. Because he has the Firelight trait, he is incredibly mobile.

Expert Insight: Ekko is the best recipient of the "Lucky Item" mechanic at 6 Scrap. If you leave a Sparring Glove on him, the game is highly likely to give him a Hand of Justice or a Jeweled Gauntlet, both of which are phenomenal for his kit.

Rumble (5-Cost: Scrap, Junker King, Sentinel)

Rumble is the legendary capstone. His ability to call down a missile rain that burns and wounds enemies makes him a massive upgrade over Powder in the late game. As a Junker King, he has unique interactions with the shop that allow you to further optimize your board.

The Strategic Roadmap: How to Play Scrap

Playing Scrap isn't about hitting "Refresh" until you find the units; it's about managing the flow of the game.

Early Game: The Component Advantage (Stages 2-1 to 3-2)

In the early game, your goal is to win-streak. Because Scrap gives you "extra" items through conversion, you should almost always be stronger than an opponent with the same number of units.

Don't "Slam" Everything: Normally, TFT guides tell you to build items immediately. In a Scrap build, you want to keep at least 2-3 components loose.
Distribute Components: Spread your loose components across your Scrap units. Giving one component to Trundle and one to Powder is better than giving two to Trundle, as the 2-Scrap trait only converts one component per round.

Mid Game: The Transition (Stages 3-2 to 4-1)

This is where many players fail. You need to decide if you are rerolling for 3-star low-cost units or pushing for Level 8.

The Reroll Path: If you have many Trundles and Powders, stay at Level 5 or 6 and slow-roll. This version of the Scrap build relies on the raw stats of 3-star units combined with the Scrap shield.
The Fast 8 Path: This is generally more reliable. Use Ziggs and Gangplank to hold items for Corki and Ekko. Maintain a healthy economy and aim to hit Level 8 at Stage 4-2 with at least 40-50 gold to roll for your 4-cost carries.

Late Game: The Vertical Cap (Stage 4-5 and Beyond)

Once you hit 6 Scrap, the game changes. Your objective is to reach Level 9 to find Rumble and potentially hit the 9 Scrap chase trait if you have a Scrap Emblem.

Positioning: At this stage, positioning is vital. Place Ekko on the same side as the enemy's primary carry. Position Corki in the opposite corner to ensure he has time to ramp up his missiles.

Mastery of Itemization: The Scrap Way

Itemization in a Scrap build is a delicate balance between "Hard Slams" and "Scrap Slots."

Core Items (Build these no matter what)

You need a few permanent items to stabilize your carries:

Corki: Infinity Edge and Last Whisper (if you aren't hitting Artillerist 4).
Ekko: Ionix Spark (to shred MR for himself and Ziggs/Rumble) and a healing item like Bloodthirster.
Trundle/Blitzcrank (Sentinel/Bruiser frontline): Sunfire Cape or Redemption.

The "Scrap Slot" Philosophy

For every Scrap unit that isn't your primary carry, you should leave one item slot empty and fill it with a single component.

Tear of the Goddess: Great on Powder or Ziggs for early casts.
Needlessly Large Rod: Excellent on Ekko or Rumble.
B.F. Sword: Good on Gangplank or Corki.
Recurve Bow: Surprisingly good on Trundle, as the Scrap trait can turn it into a Titan's Resolve.

What are "Lucky Items"?

At 6 Scrap, the converted items become "Lucky." This means the system checks the unit's tags.

If the unit is a Tank (Trundle), a loose Chain Vest is more likely to become a Bramble Vest or Stoneplate rather than a Titan's Resolve.
If the unit is a Physical Carry (Corki), a loose Sword will almost always become a Deathblade or Giant Slayer. This mechanic significantly reduces the RNG variance that plagued Scrap in previous sets.

Augments and Anomalies: Powering Up the Junk

In Set 13, Augments and the Anomaly mechanic can take a Scrap board from "Top 4" to "First Place."

Best Augments

Scrap Crest/Crown: These are mandatory for hitting the 6 or 9 vertical breakpoints.
Cybernetic Uplink/Shell: Since Scrap encourages spreading components, the Cybernetic series (which gives stats to units with items) provides massive value.
Binary Airdrop: This is the "hidden OP" augment for Scrap. It gives a third item to units with two items. Combined with Scrap's conversion, your entire board will be fully itemized.
Salvage Bin: Allows you to break down completed items into components. This is perfect for readjusting your Scrap slots as you find better carries.

Choosing the Right Anomaly

The Anomaly at Stage 4-6 should be used to buff your primary carry (Corki or Ekko) or your legendary (Rumble).

For Corki: Look for damage multipliers or attack speed buffs. Anything that allows him to cast his missiles faster is a priority.
For Ekko: Defensive anomalies like "Stone Skin" or "Diving In" are great because they allow him to survive in the enemy backline longer.
For Rumble: "Giant-Sized" can turn him into a terrifying raid boss that burns the entire enemy board.

Composition Variants

While 6 Scrap is the standard, you can flex based on your emblems and high-rolls.

The Scrap-Artillerist (Standard)

Core: 6 Scrap, 2 Artillerist (Corki + Tristana/Ezreal).
Frontline: Trundle, Gangplank, and a secondary Bruiser or Sentinel like Illaoi.
Why it works: This is the most balanced version, providing a mix of AoE armor shred and high burst.

The Scrap-Family Reroll

Core: Powder, Violet, Vander (Family core) + Scrap units.
Strategy: Reroll at Level 5 for 3-star Powder and Vander. Use the Family bonus to reduce mana costs and increase survivability. This is a "tempo" board meant to end the game early.

The 9 Scrap "Exodia"

Core: All Scrap units + 2 Scrap Emblems.
Why it works: Radiant items are fundamentally broken. A Radiant Infinity Edge on Corki will one-shot most backline units. If you hit 9 Scrap, it is almost a guaranteed first place.

Common Mistakes to Avoid

Over-Slamming: Building three full items on every unit. You lose the entire value of the Scrap trait if there are no open slots for conversion.
Poor Component Distribution: Putting three loose components on one unit. Only one (or three, depending on the tier) will convert. Spread them out!
Ignoring the Frontline: Many players focus so much on Corki and Ekko that they forget Trundle and Gangplank need items too. A 4000-HP shield is useless if the units underneath it have zero resistances.
Not Scouting for Enforcers: Enforcers can detain your highest-HP unit. Since Scrap units have massive shields (which count towards "effective HP"), your carry might accidentally get detained. Adjust positioning accordingly.

How to Counter the Scrap Build

If you find yourself playing against a Scrap player, here is how you beat them:

Giant Slayer: This is the hard counter. Since Scrap provides massive shields, Giant Slayer’s damage amplification (which triggers on high-health targets) will be active against almost every Scrap unit.
Shield Breakers: Items like Guardbreaker are incredibly effective.
Burst Damage: Scrap relies on the shield to survive the initial burst. If you can out-damage the shield in the first 5 seconds (e.g., using a high-power Sorcerer or Sniper build), the Scrap units are actually quite squishy.

Frequently Asked Questions (FAQ)

What is the best item for the Scrap conversion slot?

It depends on the unit. For Ekko, a Tear or Glove is best. For Corki, a Sword or Bow is best. For Trundle, a Belt or Chain Vest is best.

Does the Scrap shield stack with other shields?

Yes. The Scrap shield stacks with items like Bloodthirster or Crownguard, and other trait shields like Sentinel.

Is Scrap 6 better than Scrap 4?

Absolutely. The "Lucky Item" mechanic at Scrap 6 is a massive power spike because it ensures your converted items are actually useful.

Can I play Scrap without Rumble?

You can, but your late-game ceiling will be much lower. If you don't find Rumble, you usually need to transition into a 4 Scrap + high-cost legendary board (like adding Jayce or Malzahar).

Conclusion

The Scrap build in TFT Set 13 is a masterclass in game design, rewarding players who can think on their feet and manage their resources effectively. By leveraging the shield mechanic for early-game survivability and the "Lucky Item" conversion for late-game power, you can create a board that is both incredibly tanky and deceptively high-damage.

Remember the golden rule of Scrap: Keep it messy. Don't be afraid of loose components, and always look for ways to maximize the number of converted items on your board. Whether you are rerolling for Powder or pushing for a Level 9 Rumble board, the Scrap trait provides a path to victory for those who know how to turn junk into gold.
