Memory Theft

Targeted discard usually stops at the hand: you reveal the cards, pull one, and the rest stay put. This one reaches past the hand into exile, where a particular flavor of deferred value waits. When a card that has an Adventure is cast on its Adventure half, the card itself goes to exile until its owner casts the other half from there; that stored second cast is a built-in two-for-one. The rider here follows into that holding zone and drops the exiled Adventure card straight into its owner's graveyard, taking the whole card with it rather than leaving the second half waiting to be spent. That makes it hand disruption with an answer to a mechanic most discard cannot touch, which is also exactly why it plays so narrowly away from the environment that mechanic defines: against a deck with no exiled Adventure cards, the second clause is dead text. What remains is a leaner cousin of Coercion, three mana to strip a card from the revealed hand, but restricted to nonland targets rather than anything you see. The design is hate stitched directly into a staple keyword: a discard spell that knows precisely what it was printed alongside and does its most interesting work only there, with the nonland clamp keeping it pure disruption everywhere else.
