Akroma's Blessing

Mass protection has a chronic flaw: it is a blowout when the board is set up for it and dead weight when it is not, so it rots in hand against the wrong opponent. The cycling cost answers exactly that. On a turn where the chosen color buys nothing, you pay a single white and trade the slot for a fresh card. When the board does line up, the same instant fogs an alpha strike (protection strips the attackers' damage and breaks any targeted spell pointed at your team in one motion), dodges a sweep of burn if you name red, or evades targeted black removal across the whole side. Note the boundary: protection works against the four definitions (damage, enchanting or equipping, blocking, targeting), so it will not save anyone from a global like Wrath of God, which neither targets nor deals damage; this is a shield against pointed interaction and combat, not against destroy-based board wipes. Choosing a color rather than naming a permanent keeps the answer broad without making it universal. The pull at the heart of mass protection is real: it wants to be cheap enough to leave mana open and swingy enough to win on its own, two goals that usually fight each other. Cycling lets the card be both, depending on which turn it shows up, and that is why it never sits dead.
