Dominaria's Judgment

Protection from every color at once is the kind of blanket the game almost never hands out, and the price here is paid in manabase rather than mana value: each color clause switches on only if you control the matching basic land type. A mono-white build gets protection from white and nothing else, which fends off almost nothing; a deck running lands that carry all five basic types (and that need not be five basics, since shocklands, Triomes, and other typed nonbasics each satisfy their clause) turns this into near-total invulnerability for a turn, with every colored blocker phased out of combat math and every color-aligned removal spell rendered inert. The instant timing is what gives it teeth: the protection resolves in response to a blocked attack or a kill spell already on the stack, letting it ambush a combat step or strip the legal target out from under a removal spell that has already chosen one. The design lesson is that the payoff scales with how greedily your lands reach across the color pie: it rewards the typed, multicolor manabase that focused decks deliberately avoid, and it gates a board-saving, attack-winning swing behind a land mix most decks never assemble. That tension is why it reads as a build-around rather than a maindeck answer, a card whose ceiling lives in five-color piles and whose floor in a tight two-color deck is close to nothing.
