Death Denied

Bulk creature recursion at instant speed, with the X scaling the refill to the size of your graveyard rather than the size of your hand. The recovery line is the whole pitch: a board wipe resolves, your creatures hit the yard, and you rebuy three or four of them at the end of the turn before untapping with a full grip. That is a rebound most reanimation effects can't match, because they bring back one body at sorcery speed and this returns a fistful instantly. As a standalone spell it is unspectacular: returning creatures to hand still costs the mana to recast them, so it reads as tempo loss dressed up as card advantage, and those bodies will be summoning sick when they land just as any freshly cast creature would. What redeems it is the timing and the unbounded X. Returning to hand instead of the battlefield is a deliberate choice: it routes the creatures back through the cast step, so you pay them out one at a time on your own schedule and trigger anything that cares about casting rather than dumping them all at once. The Arcane typing is the one line not doing recursion math; it makes the spell a legal target for splice onto Arcane, so as you cast it you can reveal another Arcane card from your hand and pay its splice cost to staple that spell's effects onto the same resolution. The recursion stands on its own; the Arcane tag is a hook for whatever else you are holding to ride along on the same cast.
