Is Deflect good in Slay the Spire 2?

In Slay the Spire 2, Deflect is a common skill from the Silent card pool. Its effect: Gain 4 Block. The data flags it as a weaker pick, settling at D tier — usually one to pass on unless your deck specifically wants it.

Over 645 tracked runs its win rate sits at 23.7%, 9.7% ahead of the 14.0% all-deck baseline. It sees niche play, included in only 5.6% of eligible runs. Taken 21.4% of the times it is offered, it lands close to neutral on the pick-versus-skip split: 21.9% for runs that took it against 23.5% for runs that passed, a -1.6% pick lift over 530 decided runs. Within Silent runs it’s drafted 21.7% 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 +25.1% when the two share a deck. On the relic side, Toolbox is its standout companion, worth a +37.0% win-rate swing alongside it. It costs 0 energy, gets upgraded 24.3% of the time, and tends to be picked up near floor 14.

Its most common run-ender is Test Subject Boss, finishing 5.9% of the runs it shows up in. See the synergies, class split, and threats below for the full picture of where Deflect fits a Silent deck.

Pick or Skip: Deflect

Taken 638 times out of 2975 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.
