Demonic Ruckus

What kills aura decks is card disadvantage: the target dies, you're down two cards, and the whole plan folds to a single removal spell. This design answers both structural leaks in the archetype. The graveyard trigger refunds a card whenever the Aura hits the yard (whether the creature dies with it or the enchantment is destroyed on its own), so the two-for-one that punishes most aura strategies is defused into an even trade. Plot answers the other half, the tempo tax of committing a creature and then burning a whole turn suiting it up: pay red on a quiet turn, then drop the buff for free later, sidestepping the vulnerable window where your attacker is sitting undressed. The stat bump plus menace and trample turns a modest body into something that punches through gang blocks and mops up a stalled board. It's a red aggressive aura built by someone who understood exactly why the archetype has always been a trap, then patched it: the removal-blowout risk is neutralized by a cantrip on death, and the tempo cost is neutralized by casting it off a previous turn's investment. The floor is a card-neutral trick that occasionally makes a creature better; the ceiling is a free, evasive buff that trades up in combat and replaces itself when it finally trades down. Note the shape of that trigger, though: it draws exactly once, on the way to the graveyard, and there is no recursion to loop it.
