Mistform Dreamer

The Mistforms are an early-block answer to a set built on creature types: a small cycle of Illusions that pay a single mana to declare themselves whatever tribe the moment requires. This one carries the keyword that matters, flying, on the cheapest evasive frame in the group, which means it slots into any tribe's curve as an attacker while still answering lord effects and tribal payoffs on demand. The shape-shift justifies the cycle's existence in a set obsessed with Goblins, Elves, Soldiers, and Clerics: the activation is repeatable and the type choice is unrestricted, so a single creature can be a Goblin for a sacrifice trigger this turn and a Wizard for a draw trigger the next. The cost it pays is fragility. A 2/1 dies to almost anything, and the type-change lasts only briefly, so it never holds a permanent identity; you rent the tribe, you do not own it. That made the design a curiosity in its own era and a recurring footnote since: a body whose value is entirely contingent on what tribal machine it plugs into, doing nothing in a deck with no types to care about and quietly enabling a whole engine in a deck that does.
