Metamorphose

Tempo bounce that pretends to be generous. Sending a permanent to the top of its owner's library is a sharper kind of removal than hand-bounce: it costs the opponent their next draw, not just a replay, and it answers anything that has resolved, including tokens (which evaporate on the way up) and indestructible threats that conventional removal cannot touch. You choose what gets sent, which is most of the value. The trade is even on cards (you spend one, they lose a draw step), but the second clause is the real friction: the targeted opponent may immediately put an artifact, creature, enchantment, or land from hand onto the battlefield (planeswalkers and battles excluded). That is the design tension. You pick what leaves, but you hand the opponent a free deployment, and because that permanent is put into play rather than cast, it sidesteps the stack entirely. There is no countering it, no responding to it; it simply arrives during resolution. Note that the giveback comes from hand, not the library, so the opponent cannot immediately redeploy the thing you just bounced; it sits on top of the deck, a draw away. The skill is reading the opponent's hand: against a stranded board or an empty grip the second clause does nothing, while against a developed hand you may be trading their worst permanent away for their best. Threading that needle is the reason the card reads as a fair-removal spell wearing a tempo spell's clothes.
