Klaw, Sonic Subjugator

Targeted discard fights a familiar scaling problem: a strip that's brutal on turn two often does nothing on turn ten, when the opponent has emptied their hand and you're left picking through a card or two. This design leans the other way. The reveal count keys off creature cards in your own graveyard, so a strip that starts as a plain reveal-one-pick-one (one plus zero, with an empty yard) widens as the game grinds on, giving you a fuller look at the opponent's hand precisely as an attrition deck fills its graveyard. It's hand disruption tuned for the long game rather than the fast one, paying off the board states where discard usually goes stale. Two things sharpen it past a bare Coercion effect. First, the strip is stapled to a body, so the floor is a creature you were casting anyway rather than a spell that does nothing else afterward. Second, the enters trigger loops: any blink, bounce, or reanimation that returns it repeats the discard, and every creature that dies feeding the yard makes the next reveal reach deeper. The clever pivot is that the effect measures your own graveyard rather than the opponent's remaining cards, so it never becomes a topdeck tax on a shrinking hand; it rewards a graveyard you were already stocking, while the body and its black cost are priced as if that graveyard were empty.
