Cauldron's Gift

Reanimation with a self-mill payload folded into the same card, which is the design conceit that makes this more than a slow raise-dead. The adamant clause pays out only if you commit three black mana to the cast, and its reward (milling four) is a benefit rather than a cost here: those four cards deepen the graveyard you are about to draw from, so the spell can fill its own target and cash it in on the same turn. That folds the two halves of a reanimator strategy (get a big creature into the bin, get it back onto the battlefield) into one sorcery, at the price of committing hard to black mana. The +1/+1 counter is a small sweetener that also nudges the card away from cheap value loops toward returning something worth returning. What keeps it from being a true engine is the sorcery speed and the five mana: there is no ambush, no end-step surprise, no instant-speed reanimation off a fresh death. You pay full price at your own turn and get the creature back a beat later. As reanimation goes it is honest and self-sufficient, a one-card version of a plan that usually needs two.
