Living End suspends its namesake sorcery for {2}{B}{B} and then reanimates its whole discarded creature suite for free, so Tormod's Crypt and Nihil Spellbomb are excellent if timed right after they've pitched creatures via cycling-style effects but before the suspended Living End resolves — this denies the free reanimation entirely. Unholy Heat is strong post-Living End cleanup: with delirium's 6 damage it kills Endurance (3/4), Subtlety (3/3), Shardless Agent (2/2), Curator of Mysteries (4/4), and Oliphaunt (6/4), though it will not be enough for Generous Ent (5/7) or Waker of Waves (7/7). Since their whole plan hinges on the graveyard, exiling it at the right moment is far more valuable than answering individual creatures after the fact. Keep our clock going in case we need to just race a turn faster than their suspend timer.
