Planeswalkerificate
One line does all the damage: toughness becomes loyalty. Because a planeswalker's loyalty is permanent and a creature's toughness is not, that substitution quietly rewires the whole rules engine. The enchanted creature stops blocking, stops healing at end of turn, and starts spending itself down through minus abilities the way any planeswalker pays loyalty, except its starting count is whatever body you strapped the Aura onto. A wall becomes a durable engine; a two-toughness creature gets two minus activations (dropping to one, then to zero) before it dies, and every point of combat damage it takes permanently shortens that clock. The three granted abilities read like a compressed mono-red toolkit: ritual mana on the plus, impulse draw on the first minus, and a scalable burn finisher on the minus-X that literally spends the creature's remaining toughness to deal its damage. The design lives by stressing two rules subsystems that were never meant to touch: damage marked on a creature now permanently drains a planeswalker's loyalty, and the reminder text has to spell out that toughness "doesn't heal at end of turn" because otherwise the whole thing wouldn't function. It belongs to the un-serious register of Magic's silver-adjacent releases, where the goal is to take a tightly governed card type and bolt it somewhere it doesn't belong just to watch the seams show. The seam here is the assumption every player carries without noticing: that combat damage on a permanent eventually wipes clean.
