Olivia, Crimson Bride

The reanimation costs nothing but an attack step, which is where this design earns its aggression. Where most graveyard-recursion spells demand a chunk of mana on the main phase, this one folds the return into a combat trigger and drops the target onto the battlefield already tapped and attacking: a fatty that would normally have to survive a turn before swinging arrives committed to the red zone the moment it returns. Note that the returned creature never gains haste; it simply enters mid-combat with its attack already declared, which sidesteps summoning sickness for that swing without granting the keyword. The trigger fires on attack, not on damage, so even a chump-blocked swing still drags a body out of the yard. What balances the aggression is the leash: each returned creature carries a rider exiling it the moment you stop controlling a legendary Vampire, tethering the whole engine not to any single body but to keeping a legendary Vampire on the board at all. Sweep the Vampires and everything dragged from the yard evaporates. That conditional is load-bearing, converting permanent stacking reanimation into value contingent on maintaining a tribal presence. The real cleverness is the snowball: a graveyard stocked with expensive attackers spills more bodies onto the battlefield with every declared attack, rather than reanimating once and coasting. It is aggressive reanimation, a category that usually wants to sit back, rebuilt as a combat engine that grows its army each time it swings.
