Night Incarnate

Take Nekrataal's death-trigger removal, split it off from the body, and hand the death-timing to the caster: that is the trade this offers. The mechanism runs backward from most evoke elementals. Where the classic Lorwyn evokers fire their trigger on the way in, this one wants to leave the battlefield, and the evoke sacrifice supplies exactly that departure the moment it resolves. So the evoke line is the fast one: pay , sacrifice the elemental on entry, and the -3/-3 fires immediately when you just need the board gone. It is the hardcast that delays the sweep. Cast the five-mana 3/4 and the -3/-3 waits behind a deathtouch blocker until something kills it or you choose to bounce or sacrifice it yourself. That patience is the real design lever. A hardcast copy is a removal spell you can hold in play, threatening to wipe every small creature the instant it dies, which reshapes how an opponent attacks into a deathtouch body they cannot profitably trade with. Deathtouch on the front half also quietly widens the trigger's reach: even a 3/4 trades up in combat before the -3/-3 ever clears the rest of the board. It is a modular piece of black interaction that asks you to decide, every time, whether you are buying a sweeper now or a blocker with a delayed wrath stapled to it.
