Uril, the Miststalker

The structural problem every Aura strategy has fought since the beginning is the two-for-one: a single targeted removal spell eats the enchanted creature and every Aura riding it, turning a multi-card investment into one dead body. Hexproof is the cleanest possible answer to that exact line. It shuts off targeted removal while the creature is on the battlefield, which is the precise tool an Aura pile loses to most often. The protection has edges worth stating: a counterspell still catches it on the stack, and sweepers, edicts, and blocks all remain open, since none of those name the creature. What it denies is the spot-removal answer that would otherwise be free. The +2/+2-per-Aura clause then makes each enchantment pay twice: once for the Aura's own effect, once for the body's scaling, so a couple of buffs already represent a lethal swing on a frame that no longer dies to a kill spell. The design coheres because protection and payoff point at the same axis. The harder you commit Auras, the more the centerpiece resists removal and the faster it closes, with counterplay narrowed to effects that never target it. Three colors of enchantment support converge here: red's combat enablers, green's trample and resilience, white's protective Auras. That convergence is why hexproof voltron became shorthand for a deck that asks the opponent to find a wrath or lose.
