Majestic Metamorphosis

The wrinkle is what "becomes" does under the layer system: this sets a target's stats to 4/4 and rewrites its types and subtypes, so a token, an artifact, or an opposing creature all end up as the same flying Angel until end of turn. It grants flying without touching the target's existing text box, which is why the trick is quieter than it looks: keywords and triggered abilities the target already had still apply, and any auras or equipment attached to it keep modifying the new 4/4 body, since stat-setting effects land before the boosts they hand out. What actually changes hands is the body and the type line. Aimed at your own token, it becomes an evasive threat with a cantrip attached; aimed at an enemy bomb whose whole plan was a big printed body, it shrinks to a manageable 4/4 that no longer outclasses your board. The "becomes an artifact" clause is the sneaky part: for the turn, a creature it targets is a legal mark for artifact removal and artifact-only effects it would otherwise dodge, and a creature you own gains an artifact typing it can leverage the same way. The replacement cantrip is what guarantees the flexibility is never a dead slot, whether the cast was aggressive, defensive, or purely political.
