Is Twin Strike good in Slay the Spire 2?

In Slay the Spire 2, Twin Strike is a common attack from the Ironclad card pool. Its effect: Deal 5 damage twice. The data flags it as a weaker pick, settling at D tier — usually one to pass on unless your deck specifically wants it.

Over 862 tracked runs its win rate sits at 17.2%, 3.4% ahead of the 13.8% all-deck baseline. It sees niche play, included in only 4.1% of eligible runs. Offer data argues the other way: taken 19.2% of the time it is shown, runs that picked it win 17.6% against 21.6% for runs that passed — a -4.0% pick lift across 732 decided runs. Within Ironclad runs it’s drafted 18.4% of the time, making it a regular part of that class’s decks. Decks that include it run about 1.3 copies on average.

Its standout pairing so far is Mad Science, which lifts its win rate by +26.9% when the two share a deck. On the relic side, Royal Stamp is its standout companion, worth a +35.4% win-rate swing alongside it. It costs 1 energy, gets upgraded 30.2% of the time, and tends to be picked up near floor 11.

Upgrading the card adds +2 Damage to its stat line. Of the runs that drafted it, 145 ended in victory against 697 deaths and 20 abandons. Its most common run-ender is Kaiser Crab Boss, finishing 7.2% of the runs it shows up in.

Pick rate when offered counts offers, not runs: out of every time the game put this in front of a player, how often it was taken. It is not the same number as the share of runs that end up containing it.

Pick lift is the sample-adjusted gap between runs that took the option and runs that passed on it. It is the fair way to rank choices, because raw win rates put the smallest samples on top.
