Harlequin Collection trade-ups in CS2: five live contracts with float bands in the write-up. Cost, expected value, and profit update live on each card from the Trade-Up Database.

Harlequin is a weekly Care Package weapon collection. Ten matching inputs trade into one skin of the next rarity inside the Harlequin pool, including the Classified M4A1-S | Party Animal. Every card below deep-links into the Trade-Up Calculator so you can recheck floats, fees, and outcome prices before you buy.

For other ladders, see Achroma, Boreal, Train 2025, Fever, Sport & Field, Gallery, Ascent, Kilowatt, Souvenir trade-ups, and knife trade-ups.

Selection rules for this post

  1. Screened at publish for positive live expected profit and fully priced outcomes
  2. Optimal float span at least 0.03 when markets allow
  3. Distinct rarity and wear bands across the picks
  4. Input asks stay tight across marketplaces when books allow (2nd-cheapest near cheapest)
  5. The article lists skins, float bands, and pool notes only
  6. Live cards show current cost, EV, and profit, and open in the Trade-Up Calculator

  5. UMP-45 | Warm Blooded (Battle-Scarred), optimal float 0.3800 to 0.4500

How Harlequin Collection trade-ups work

  1. Add 10 skins of the same rarity from the Harlequin Collection (or a valid mix with other collections if you intentionally split odds).
  2. Collection odds follow the share of each input.
  3. Output float follows the average float of your ten inputs and the outcome float range.
  4. Buy inside the printed optimal float range, set your sell fee, then confirm EV on the live card or in the Trade-Up Calculator.

How to run the contract

  1. Confirm cost, expected value, and expected profit after your fee on the live card.
  2. Stay inside the optimal float range. Wider spans leave more room when listings move.
  3. Use Open in Calculator on the card when you want to swap one filler or reprice the contract.
  4. Recheck prices right before you commit. Collection books still move with supply and listing depth.

FAQ

Can you trade up Harlequin Collection skins in CS2?

Yes. Ten skins of one rarity return one skin of the next rarity from the Harlequin outcome pool, the same rule as other weapon collections.

How do you pick these Harlequin trade-ups?

Picks were screened for fully priced outcomes, a usable optimal float span, positive live expected profit, and tight input listings across marketplaces. Always recheck cost and EV on the live card.

Where do I see live cost, EV, and profit?

On each live trade-up card below, or by opening the same recipe in the Trade-Up Calculator. This article does not freeze dollar costs or profit percents in the prose because those move with the market.

What is the top Harlequin Collection trade-up target?

M4A1-S | Party Animal is the Classified ceiling. Restricted inputs such as USP-S | Sleeping Potion can trade into that M4A1-S when the contract stays inside a profitable float band.

Where else should I look?

Trade-Up Calculator, Trade-Up Database, Boreal Collection trade-ups, Train 2025 Collection trade-ups, Fever Collection trade-ups, Sport & Field Collection trade-ups, Gallery Collection trade-ups, Ascent Collection trade-ups, Kilowatt Collection trade-ups, Souvenir trade-ups, and CS2 knife trade-ups.

Final notes

Harlequin books shift with marketplace depth. Re-open each card before you buy, set the fee for where you sell, and stay inside the float band. Build or tweak any of these crafts in the Trade-Up Calculator, or browse more contracts in the Trade-Up Database.
