Vile Redeemer

The flash here is doing something stranger than survival: it lets a token-payoff that counts creatures dying this turn fire at instant speed, when nearly every other card that reads the same trigger is stuck at sorcery speed and forced to set up the death and the payoff across two turns. The sequence is specific, though, and the timing matters. The cast trigger looks at nontoken creatures that have already died under your control this turn, so you wait: let the opposing sweeper resolve, watch your board die, then cast this in the aftermath with the bodies already in the graveyard. Cast it before the wrath and the trigger reads an empty count. The payment is the cost that keeps the conversion honest, since it asks for a colorless source rather than just untapped lands, and the floor you accept for that ceiling is a 3/3 body that contributes nothing against an empty board. The cleverest part is the loop the design implies: each Eldrazi Scion it makes can sacrifice for , which is precisely the resource the cast trigger demanded in the first place, so a sudden wide board folds back into the colorless mana that runs the rest of an Eldrazi shell. It sits with the small set of devoid creatures built specifically to turn the board wipe an opponent was counting on into the worst card left in their hand.
