Is Countdown good in Slay the Spire 2?

In Slay the Spire 2, Countdown is an uncommon power from the Necrobinder card pool. Its effect: At the start of your turn, apply 6 Doom to 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 343 tracked runs its win rate sits at 24.0%, 10.0% ahead of the 14.0% all-deck baseline. It sees niche play, included in only 3.0% of eligible runs. Taken 29.4% of the times it is offered, it lands close to neutral on the pick-versus-skip split: 25.7% for runs that took it against 27.0% for runs that passed, a -1.3% pick lift over 265 decided runs. Within Necrobinder runs it’s drafted 15.3% 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 Oblivion, which lifts its win rate by +22.1% when the two share a deck. On the relic side, Forgotten Soul is its standout companion, worth a +23.7% win-rate swing alongside it. It costs 1 energy, gets upgraded 34.6% of the time, and tends to be picked up near floor 15.

Of the runs that drafted it, 82 ended in victory against 260 deaths and 1 abandons. Its most common run-ender is Decimillipede Elite, finishing 7.3% of the runs it shows up in. See the synergies, class split, and threats below for the full picture of where Countdown fits a Necrobinder deck.

Pick or Skip: Countdown

Players take Countdown in 29.4% of the 1025 offers it appears in; those runs win 25.7% against 27.0% for runs that passed, a pick lift of -1.3% over 265 decided runs.

Taken 301 times out of 1025 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.
