Fight On!

Regrowth for creatures, doubled, and that doubling is the whole design. Black has always had cheap single-target creature recursion (Raise Dead and its many descendants), but paying three mana buys the second body, and the second body is where the math turns. As instant-speed card advantage it wants a graveyard already stocked with things worth returning: two creatures that died in combat, two sacrifice engines fed to their outlets, a pair of value creatures traded away and clawed back before you untap. The instant timing matters more than it looks. It lets the recursion happen after blocks, after a board wipe resolves, after an opponent has committed to a line assuming those creatures are gone for good, which turns a two-for-one into a tempo swing rather than a slow grind. What keeps it fair is that it only speaks to creatures and only reaches the graveyard: no self-mill, no digging, no reach for a key noncreature spell you actually need. You have to build the yard yourself, and the card rewards a deck that treats its graveyard as a second hand rather than one that stumbles into recursion by accident.
