Omen of the Dead
Raise Dead has always cost one black mana and always given up something for the low rate: sorcery speed, no board presence, a single line of text and nothing else. The design move here is to bundle that recursion into a permanent with flash, which changes the timing math entirely. You can hold up the black mana as if for an instant, then decide during your opponent's end step or in response to removal whether to buy back the creature; the recursion arrives at a window the sorcery-speed version never reached. What pays for the flexibility is that the card lingers as an enchantment rather than vanishing on resolution, and that residue does real work. Once the creature is back in hand, the leftover permanent is not dead weight: it can be cracked later for a scry, folding a smoothing effect into a card that has already done its main job. That two-stage structure (an immediate value trigger, then a delayed sacrifice payoff) is the shape the whole Omen cycle shares, but the split here is unusually clean: recursion first, card selection whenever you want it, with the enchantment sitting on the battlefield as a stored option in between. It is a small card doing careful work, trading the raw efficiency of the classic reanimation one-drop for reach across turns and a bit of dig on the back end.
