In Slay the Spire 2, Neurosurge is a rare power from the Necrobinder card pool. Its effect: Gain Energy. Draw cards. At the start of your turn, apply 3 Doom to yourself. 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 196 tracked runs its win rate sits at 39.2%, 25.3% ahead of the 13.9% all-deck baseline. It sees niche play, included in only 1.7% of eligible runs.

Within Necrobinder runs it’s drafted 8.6% of the time, making it a regular part of that class’s decks. Decks that include it run about 1.1 copies on average.

Its standout pairing so far is Transfigure, which lifts its win rate by +22.6% when the two share a deck. On the relic side, Leafy Poultice is its standout companion, worth a +25.9% win-rate swing alongside it. It costs 0 energy, gets upgraded 31.3% of the time, and tends to be picked up near floor 19.

Its most common run-ender is Test Subject Boss, finishing 6.1% 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.
