Is Hellraiser good in Slay the Spire 2?

In Slay the Spire 2, Hellraiser is a rare power from the Ironclad card pool. Its effect: Whenever you draw a card containing “Strike”, it is played against a random enemy. The data flags it as a weaker pick, settling at D tier — usually one to pass on unless your deck specifically wants it.

Over 63 tracked runs its win rate sits at 27.1%, 8.2% ahead of the 19.0% all-deck baseline. It sees niche play, included in only 1.7% of eligible runs.

Its standout pairing so far is Not Yet, which lifts its win rate by +21.1% when the two share a deck. On the relic side, Vajra is its standout companion, worth a +24.0% win-rate swing alongside it. It costs 2 energy, gets upgraded 54.7% of the time, and tends to be picked up near floor 16.
