Ethereal Armor

The payoff that makes a board full of single-target Auras worth the card-advantage risk. Voltron strategies live in fear of the two-for-one: spend a card pumping a creature, lose the creature, lose both. This one mana does not change that math (if the creature dies to targeted removal, you still eat the trade), but it raises the reward high enough that the gamble pays. The buff scales off every enchantment you control rather than the creature it sits on, so each other permanent in play (the other Auras, the cheap pump, anything that reads "enchantment") feeds it for free. The ceiling is set by your enchantment count, not by anything printed on the card itself. First strike is the quiet other half of the design: a buffed attacker that strikes first turns combat into a one-sided kill, which is exactly the math an enchantment-aggro deck needs while it races to close before its cards-in-play disadvantage catches up. What powers it also limits it: with one or two enchantments out it is a minor trick, and it demands a deck built around permanents that invite removal. That commitment is the whole archetype. For white aggro, this reframed a pile of Auras from a stack of blowout risk into a coherent racing plan, the payoff that made the all-in enchantment build worth the cards it puts on the line.
