Pure Intentions
Built as a dedicated answer to a single line of attack: the opponent who pries open your hand with discard and then wins by denying you the cards to rebuild. The effect is asymmetric by construction. It does nothing against your own discard, nothing against costs you pay yourself, nothing against milling. It fires only when an opponent's spell or ability forces the discard, a narrow window but exactly the one where losing your hand hurts most. Because it is an instant, you hold it up for a single white mana and turn a Hymn-style hand-strip into a temporary inconvenience: the discarded cards return from your graveyard to your hand the instant the trigger resolves, so the opponent never actually separates you from your hand. The second clause closes the obvious gap. If this card is itself the thing your opponent makes you pitch, it comes back at the beginning of the next end step, so they can stall it but never reliably pry it loose. The cost is its own indictment, since against any deck that does not attack the hand it is a blank, and the strategies it punishes have always been a minority of any field. As design it captures an old white instinct, protecting what is yours rather than disrupting what is theirs, the same defensive posture that produces fog effects and damage prevention. The discard-recursion angle was rarely revisited, which leaves this an unusually pointed specimen of answer-card design: dead weight in most games and a hard counter in exactly one.
