Estrid, the Masked
The first commander built to make an Aura deck function, and the design does it by treating Auras as protected assets rather than liabilities. Enchantment-based Voltron has always fought the same structural problem: the more you invest in a permanent, the more a single removal spell blows you out. Estrid's minus-one answers that directly by minting a Mask token with umbra armor, a totem-armor shell that eats the first destruction effect aimed at whatever it protects. The plus-two, meanwhile, converts an enchanted board into a mana and effect engine by untapping every enchanted permanent you control, which turns Auras that grant tap abilities or attach to mana producers into repeatable value each turn. The two abilities lean on each other: you want a wide, heavily enchanted board for the plus to matter, and the minus is what keeps that board alive long enough to build it. The ultimate is the payoff for a graveyard that fills naturally when a Voltron piece dies, reassembling your entire enchantment shell (non-Auras first, so the permanents exist before the Auras that dress them arrive) in one mill-fueled recursion. It is a narrow commander by design, asking for a deck committed almost entirely to enchantments, but within that lane it gives the archetype its first purpose-built engine: protection, ramp, and recursion all keyed to the same permanent type.
