Sothera, the Supervoid
Most edict effects tax an opponent once and move on. This one is an engine that turns every death on your side into a subtraction from your opponents' boards, and it keeps the confiscated bodies rather than letting them hit a graveyard: the creatures pool under the enchantment, exiled and waiting. The opponent still chooses what to exile, which is the standard weakness of any edict; against a board full of tokens they will feed you chaff, so this rewards a deck that can pressure opponents down to their real threats rather than an army of expendable fodder. The payoff is the second clause, and it reframes something normally undesirable as a resource. Grinding a hostile board to zero is usually the losing player's condition; here, the instant any player is left with no creatures at your end step, the enchantment immolates itself and hands you one of the exiled cards, two counters larger and now under your control, at no mana cost and immune to reanimation hate because nothing ever touched a graveyard. What keeps this from being a pure inevitability button is that the empty-board trigger fires for any player, not just an opponent: you can be the one who gets stripped, and an opponent who rebuilds resets the clock. It asks you to dictate when the board hits zero rather than to sit back and wait for attrition to do it for you.
