Arcane Adaptation

Tribal payoffs have always carried a structural risk: build around Goblins or Merfolk and the synergy collapses the moment you play a creature that does not share the type. This enchantment dissolves that constraint at the root. Rather than handing one type to one creature, it retroactively rewrites the entire creature pool you touch (board, hand, library, even your own spells on the stack) into a single chosen type, so your lords stop whiffing and your tribal anthems stop being conditional. The reach into "creature cards you own that aren't on the battlefield" is the clever part: it is not a static effect that stops at the battlefield's edge, so one copy makes every future draw count as the chosen type before you ever cast it. That same breadth turns it from a consistency patch into a combo enabler. Pair it with any effect that scales "for each creature of a chosen type" and your whole army suddenly counts as one tribe; name a type across a scattered midrange board and every disparate body starts feeding the same engine. The trade is that it does nothing on its own turn: it changes types and adds not a single point of power to the table, so it is pure setup, an enchantment whose entire value lives in the cards it makes better. Notably, the rewrite stays inside your own permission list (creatures you control, spells you control, cards you own), which means it is a builder's tool, never a way to hand an opponent's board to your removal.
