Mistform Skyreaver

The Mistform cycle's running gag was a tribe of Illusions that could pretend to be any tribe, a Onslaught-era joke about a creature-type-matters set where one creature opts out of having a fixed type at all. Most of the cycle paid for that flexibility with small, fragile bodies and modest abilities; this one is the payoff at the top of the curve, a flying 6/6 that shrugs off the typical evasion problems of fat creatures while still carrying the family's signature party trick. The shapeshifting reads as flavor more than function, but it does real defensive work: a single mana turns it into whatever its attacker or your removal-target cares about, dodging tribal lords' worth of hate or slipping past an effect that names a type. The point was never to win a tribal subgame; it was to be a hard-to-answer beater that could borrow whatever label the moment demanded and discard it before the next turn. That makes it the cycle's closer in two senses: the heaviest body, and the member that needs its type-changing least, since a 6/6 flier was already going to end games on its own.
