Ephara's Enlightenment

Most flying-granting Auras are dead weight the moment their host meets removal: you invest two-for-one and pray. This one is built to escape that trap. The bounce trigger fires off any creature you control entering, so the enchantment is designed to leave the battlefield on your terms rather than the opponent's, returning to hand to be redeployed for value: another +1/+1 counter, another evasive threat, another rebuy of the engine. That reusability is the whole design argument. A flat Aura of this rate (a counter and flying for three mana) reads as unexciting, but the recursion clause converts a normally fragile permanent into a renewable resource that compounds across a board that keeps growing. It rewards a deck pointed at creature density rather than a single bomb to suit up, since each new body is a chance to re-trigger and relocate the buff before a sweeper or spot removal can punish the commitment. The tension it resolves is the classic Aura problem of card disadvantage; here the answer is to let the Aura outlive its target by leaving voluntarily. It asks you to treat the enchantment less as permanent gear and more as a value spell you happen to cast onto a creature.
