Harmattan Efreet
A blue flier with a repeatable evasion grant attached, built for an era when blue still got to wear creature combat as a primary axis rather than a backup plan. The 2/2 body is unremarkable, but the activated ability converts a board stalled behind a defensive wall into a clock: any grounded creature can be lifted over the ground game, slipping past anything without flying or reach. The cost being repeatable matters more than the rate. With mana to spare, this is a permission engine for an entire team's worth of earthbound threats, not a one-shot trick, and it does the work at instant speed, so you can hold up the activation and decide which attacker to make evasive only once you read the table on your turn. The catch is sequencing: flying has to be granted before blockers are declared to function as evasion at all, since a creature already blocked stays blocked no matter what keyword it picks up afterward. The dual blue pips in both the cast cost and the activation pin it to a heavy-blue manabase, and that toll is what keeps the ability honest: you pay a real price each time you push damage through, and the flier's own modest stats mean it rarely survives a clean exchange to keep granting flight indefinitely. It belongs to a design lineage where blue's win condition was a small evasive body and a way to make every other creature evasive too, an approach the color has largely shed in favor of card advantage and tempo.
