Ethereal Forager

Delve usually treats the graveyard as one-way fuel: you exile instants and sorceries to shave mana off a big spell, and those cards are gone. This one turns the exile pile into a rechargeable resource. The instants and sorceries you delve away are not lost to some anonymous exile zone; they are tucked under the creature specifically, and each attack may return one to your hand. That single design choice reframes the whole cost. A card like Treasure Cruise or Murktide Regent asks you to weigh the graveyard against future graveyard-matters payoffs, spending your spent spells for a flat discount. Here the discount is a loan. You pull a counterspell or a Cryptic Command out of the yard to pay for the body, then fly it over the top a turn or two later to reclaim the very card you paid with. The tension is deliberate: the more you delve to cheapen the cast, the larger the reservoir you can attack to refill, so an aggressive reduction and a slow-burn value engine are the same act performed at different speeds. Crucially, the recursion keys off the attack declaration, not combat damage, so the loan repays itself whether or not the 3/3 gets through blockers; the flying body is there to make attacking safe and cheap, not to close games on stats. It is spellslinger recursion dressed as a delve payoff, and the graveyard it feeds on is the same graveyard it hands back.
