A-Graveyard Shift

Reanimation almost always pays for itself at sorcery speed: you commit five mana on your own turn, telegraph the threat, and hope the table doesn't have an answer before your reanimated creature attacks. The Arena rebalance version of this spell hands that whole calculus back to the graveyard. Stock five or more distinct mana values in there (an easy bar for a deck already grinding toward this effect) and the card gains flash, turning a slow, sorcery-locked reanimation spell into an end-step ambush. That shift matters more than the +1/+1 counter it staples on. At instant speed, reanimation stops being a plan your opponent gets to react to across a full turn cycle and becomes a response: you can flash a blocker back after attackers are declared, rebuild after a wrath resolves, or hold up the effect until you know it's safe. The graveyard condition doubles as a self-limiting throttle. A deck built on a handful of cheap, redundant reanimation targets stays honest at sorcery speed until it has genuinely done the work of filling and diversifying its graveyard, at which point the instant-speed mode is a fair reward for having built the engine correctly. It is a small, precise tweak to a very old effect: same body-returning payload, but the timing window is now something you earn rather than something the card hands you for free.
