Nightmare Void
Targeted hand disruption that refuses to leave the graveyard. A four-mana Coercion is an unremarkable rate on its own: the discard costs too much to anchor a turn around, and stripping one card from a hand at sorcery speed buys less tempo than the cost suggests. What changes the calculus is dredge, the mechanic that turns the graveyard into a second hand by trading a draw step for self-mill. Once this lands in the bin, it can be returned again and again, each return paid for not in mana (you still owe the to recast it) but in two cards milled from your own deck. Pure repeatable discard would be oppressive at any fair price, so the design taxes your library instead of your wallet: the loop is fueled by your own attrition. That mill is both fuel and clock. The same self-mill that earns you another casting also drives your remaining cards toward zero, so the engine that empties their hand is steadily emptying your deck. For a grinding deck willing to spend its library as a resource, the effect compounds in a way a one-shot discard spell never can, asking you to weigh, draw after draw, between refilling your own hand and stripping theirs.
