Raven's Crime

Discard effects have always faced the same fundamental problem: they trade one card for one card, and in attrition the player spending the spell runs out first. Retrace breaks that math. Each cast still strips one card from the opponent, but the spell itself never leaves; pitch a surplus land and it comes back to repeat the work. The result is a discard engine measured not in cards but in lands, which makes it ideal for the grinding manabases that already flood the board with redundant fixing. Against a control opponent emptying their hand, that single black mana plus a land becomes a recurring tax that eventually leaves them topdecking into nothing, the manlock plan dressed up as hand disruption. The retrace cost is also the throttle: every recast spends a permanent you would otherwise have played, so the engine only runs when your lands genuinely outnumber your spells, and it slows to a crawl the moment you run dry. It pairs naturally with anything that wants lands in the graveyard or rewards repeatable triggers, but the core identity is simpler than any synergy: it is a one-mana spell whose real cost is your land drops, converting excess mana into a slow, inevitable evacuation of someone else's hand.
