Moratorium Stone
Most graveyard hate built to fight recursion and flashback handles one card at a time, and that single-target throttle is exactly what dredge, escape, and reanimator engines are built to overwhelm. The cheap repeatable mode here, two mana to exile a single card, plays that familiar attrition game. The expensive sacrifice mode is the reason the card is worth remembering: it does not just exile one target, it sweeps every copy of that card name from every graveyard at once and reaches onto the battlefield to drag away any permanents sharing that name. Against a deck leaning on multiple copies of a single recursive threat, a four-of payoff in the bin and a token army of the same creature, that clause turns a one-for-one tool into a one-for-many answer. The design tension is the white-black activation cost grafted onto a colorless artifact body: the cheap mode lets any deck slot the stone for incidental hate, while the explosive sacrifice mode is gated behind a real color commitment, so you pay the artifact's low entry price to hold the option and pay again, in the right colors, only when you want the blowout. It is a name-based answer rather than a card-based one, which is a narrower axis than most exile effects work on but a far more total one when the target's whole strategy rests on redundancy.
