Exdeath, Void Warlock // Neo Exdeath, Dimension's End

The lifegain on the front side is a feint. What this card actually does is start a clock the moment it hits the battlefield, and the clock is your own graveyard. Six permanent cards in the yard by an end step and the 3/3 flips into a finisher whose power scales with everything that has died, been discarded, or been sacrificed along the way. That inverts the usual relationship between a graveyard and a creature: most yard-payoffs reanimate or recur, spending the graveyard as fuel; this one leaves the cards where they are and reads them as a live counter, so every subsequent permanent that falls into the bin makes the flipped side bigger without any further action. The trample on the back is what turns that arithmetic into damage, since a graveyard-sized body means nothing if it can be chump-blocked into oblivion. The design tension is honest: the front side wants you to sit back and gain life while permanents pile up, but the transform is a passive end-step check with a strict threshold, not something you can trigger in response to a board wipe or flip at will. You build toward it over several turns, and by the time it fires the creature is only as threatening as the attrition you have already suffered. It rewards the grindy, sacrifice-heavy shells that generate a full graveyard as a byproduct rather than a goal.
