Lumaret's Favor

A combat trick built to be cast twice, but only if a toll has already been paid this turn. The base effect is a modest +2/+4, enough to swing a race or blank a two-for-one at the combat step. What makes Infusion tick here is the timing of its check: the trigger asks whether you gained life this turn and fires on cast rather than resolution. Because this is an instant, the lifegain never needs to be scheduled turns in advance; a player can crack a life-gaining permanent during declare blockers and immediately cast this to unlock the copy in the same window. The condition rewards a board that produces life as a matter of routine, so the copy is available more often than not without contorting the sequence around it. Since the copy is created when the cast trigger resolves, the opponent sees a doubled trick coming, and the freedom to choose new targets lets the two buffs spread across separate attackers or pile onto one. It is a rate-plus-condition design aimed at green-white lifegain shells that want their incidental triggers to compound: unremarkable at face value, structurally generous for a deck already gaining life for other reasons.
