How Collections Affect Trade-Ups
The output pool of a trade-up contract is built from the collections you put in. Using 10 skins from the same collection means all possible outputs come from that collection. Mixing collections splits the output pool proportionally.
Browse all CS2 collections to see which skins are available at each rarity, or let the TradeUpX scanner find the most profitable collection for each rarity tier automatically.
