Kotose, the Silent Spider

Graveyard hate usually excises one card; this reaches past it, stripping every copy sharing that name from an opponent's graveyard, hand, and library in a single motion. That total removal is only half the design. The other half is theft: while the 4/4 remains on the battlefield, you may play one of the exiled cards, and the any-color clause lets a blue-black shell cast a red bomb or a green ramp piece pulled straight from someone else's list. Targeting a legend or a one-of does the mundane work of clearing a combo piece. Targeting a four-of does something stranger: it removes an entire playset from a deck while handing you exactly one of them to fire back, so the disruption scales with the copy count even though your access does not. The steal is conditional, not permanent. Kill the Ninja and the exiled cards go inert in exile, unplayable by anyone, so keeping the loot live means keeping a five-mana creature alive. That fragility is what stops a better answer from also being a free resource: the removal resolves once, but the reward is on lease. It reads as graveyard hate and plays as larceny, the exile framing serving mostly as the delivery mechanism for pointing an opponent's best card back at them.
