Eidolon of Inspiration
The timing is the whole design: the +2/+0 fires at the beginning of combat on your turn, before attackers or blockers are declared, so the extra power is committed while the opponent still has no information about how you intend to attack. That window sits squarely in aggression's favor. You bake in the damage before the block step, turning a race that looked even into one the defender is already behind on. The restrictions that pay for a free repeatable pump are worth naming precisely. It is +2/+0 with no toughness, lasting only until end of turn, so it never stacks across turns and does nothing to save the creature from removal: the pumped attacker dies to exactly what it always died to, and killing it is a clean one-for-one, since the boost that vanishes with it was a free trigger, not a spent card. And because the ability reads "on your turn," the Spirit contributes nothing defensively; attack into it and the 2/2 blocks like a 2/2, with no self-buff to eat damage. The body can point the boost at itself when nothing better is on the table, but it wants a larger evasive threat to ride. This is a support piece for a white beatdown plan organized around a single hard-to-block attacker: a serviceable body whose real value is shortening the clock on an unblocked flyer.
