Soulless Revival

Raise Dead has always been the floor: one black mana, one creature card back, nothing more. The splice clause reframes that vanilla regrowth as a modular attachment instead of a spell competing for its own slot. Reveal it as you cast a Kodama's Reach or a Glacial Ray and the recursion folds into that spell for a small surcharge, resolving the Arcane spell's effect and the rebuy on a single point of the stack. A card too narrow to maindeck as a hard one-of becomes worth holding precisely because it never has to be cast alone: the recursion rides alongside a spell you were always going to play, sidestepping the dead-card problem that haunts pure recursion in a deck thin on targets. The constraint is the Arcane subtype. Splice is an optional additional cost you pay as you cast an Arcane spell (reveal, pay, add the effect), so the modular value is locked to a specific spell pool rather than splashable across any deck. Outside that pool it reverts to a plain instant-speed Raise Dead, the honest baseline it was priced against. The wrinkle worth dwelling on is that splicing grants the reusability of a recurring effect without the card ever leaving your hand: because you reveal and pay rather than cast, the same copy stays put, available to bolt onto the next Arcane spell, and the one after that.
