Mayhem Power

Is Mayhem good in Slay the Spire 2?

In Slay the Spire 2, Mayhem is a rare power from the Colorless card pool. Its effect: At the start of your turn, play the top card of your Draw Pile. Right now it’s a premium pick that sits at B tier — one of the better cards you can add to a deck this run.

Over 164 tracked runs its win rate sits at 46.9%, 33.0% ahead of the 13.8% all-deck baseline. It sees niche play, included in only 0.8% of eligible runs. When it is actually offered players take it 2.2% of the time, and that looks correct: those runs win 48.5% against 26.0% for runs that passed, a +17.3% pick lift over 33 decided runs. Within Silent runs it’s drafted 0.8% 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 Prepared, which lifts its win rate by +9.2% when the two share a deck. On the relic side, Tuning Fork is its standout companion, worth a +25.0% win-rate swing alongside it. It costs 2 energy, gets upgraded 56.4% of the time, and tends to be picked up near floor 24.

Upgrading the card adds -1 EnergyCost to its stat line. Of the runs that drafted it, 75 ended in victory against 85 deaths and 4 abandons. Its most common run-ender is Queen Boss, finishing 7.3% of the runs it shows up in. See the synergies, class split, and threats below for the full picture of where Mayhem fits a Colorless deck.

Taken 35 times out of 1585 offers.

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.
