Stampede Power

Is Stampede good in Slay the Spire 2?

In Slay the Spire 2, Stampede is an uncommon power from the Ironclad card pool. Its effect: At the end of your turn, random Attacks in your Hand are played against random enemies. The data flags it as a weaker pick, settling at D tier — usually one to pass on unless your deck specifically wants it.

Over 713 tracked runs its win rate sits at 21.3%, 7.5% ahead of the 13.8% all-deck baseline. It sees niche play, included in only 3.4% of eligible runs. Offer data argues the other way: taken 24.5% of the time it is shown, runs that picked it win 21.7% against 24.1% for runs that passed — a -2.4% pick lift across 517 decided runs. Within Ironclad runs it’s drafted 15.1% of the time, making it a regular part of that class’s decks. Decks that include it run about 1.2 copies on average.

Its standout pairing so far is Demonic Shield, which lifts its win rate by +24.3% when the two share a deck. On the relic side, Sword of Jade is its standout companion, worth a +37.8% win-rate swing alongside it. It costs 2 energy, gets upgraded 58.5% of the time, and tends to be picked up near floor 15.

Upgrading the card adds -1 EnergyCost to its stat line. Of the runs that drafted it, 149 ended in victory against 551 deaths and 13 abandons. Its most common run-ender is Kaiser Crab Boss, finishing 6.3% of the runs it shows up in. See the synergies, class split, and threats below for the full picture of where Stampede fits a Ironclad deck.

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.
