Krovikan Mist

Built entirely on a feedback loop that almost nothing else in the game rewards: it counts its own kind, including itself. A lone copy is a 1/1 flyer that dies to a stiff breeze, but the body scales with every Illusion across both sides of the table, which makes it a tribal payoff that doubles as a tribal liability. The Illusion type is sparse and skittish (many Illusions carry drawbacks that punish you for caring about them), so a creature whose entire stat line is staked on board presence sits in real tension with the bodies it depends on. The design lineage is the lord-without-the-lord idea: rather than buffing other Illusions, it makes itself the beneficiary of a crowd, the way a creature whose power equals the number of other creatures of its type turns a go-wide plan into a single threat. Flying matters more here than it looks, because a board-count beater that can only swing into ground blockers tends to stall; evasion is what converts the accumulated size into damage before a sweeper resets the count to zero. The fragility is the whole bargain: the same symmetry that can make it a 4/4 or larger also means an opponent's wrath, or even their own Illusions trading off, shrinks it mid-combat. It is a card that asks you to commit to a creature type that rarely commits back.
