Pitchstone Wall

Discarding a card normally means losing it; this Wall converts the act of discarding into a salvage operation. Sacrifice the body and the card you just pitched comes back to hand, which turns any discard outlet (a looter, a rummaging engine, an upkeep cost you'd otherwise pay grudgingly) into a one-time recursion engine. It lets you discard something you actually wanted to keep and then reclaim it at the price of the creature itself, laundering a discard cost into a tutor for the top of your graveyard. The 2/5 with Defender buys the time to set that up, stalling the board while you arrange the discard you intend to redeem. What limits it is that sacrificing the Wall to a trigger spends it, and it returns only the specific card tied to that discard, so it serves a deck steering its own discards rather than one taking them off an opponent's effect or the top of its library. This is red engine-building from an era when red was briefly handed graveyard and discard tools it does not usually own, and its job was to make the discard mechanics of its time feel less like a tax and more like a resource you could spend on purpose.
