What Doom does
Doom is a stack you build on an enemy, not on yourself. Thirteen Necrobinder cards apply it.
Time’s Up is the cleanest payoff. It deals damage equal to the Doom already sitting on the target, so everything you spent earlier converts at once.
That is why spreading Doom across a room is wasteful. The card that cashes it in wants one large number, not three small ones.
Every card that uses Doom
These thirteen are the whole Doom line. The costs run from 0 to 3 Energy, and the amounts scale with the card.

Reading the amounts
Deathbringer applies 21 Doom to every enemy, and End of Days applies 29. Those are the two room-wide plays.
Oblivion and Reaper Form convert your whole turn into Doom. Oblivion adds 3 for each card you play, and Reaper Form applies Doom equal to the damage your attacks deal.
Countdown and Neurosurge do it without spending cards. Both apply Doom at the start of your turn, which keeps the stack growing while you do something else.
What supports it
Shroud turns Doom into Block, gaining 2 Block every time you apply it. Death’s Door does the same behind a condition, giving 6 Block and a bonus if you applied Doom that turn.
Those two are the defensive half. The rest of the list is pure stacking.
