Squall Drifter

A flyer that taps things is an old idea, and this is the white version priced at its most affordable: evasion stapled to a repeatable tapper that neutralizes one creature per turn for a single white mana. The 1/1 body is fragile enough that the activation, not the stats, is the whole reason the card exists, and the snow supertype is a payoff hook for an era's snow-matters cards rather than an active part of the ability. What it does on the board is pseudo-removal that never resolves: each turn it takes a creature out of the fight without trading, which over several turns can functionally remove a blocker, blank an attacker, or keep a single threat permanently offline. The flying is what keeps it relevant: it ducks the ground stall it helps create and can swing for a point when the controlling work is done elsewhere. Because the ability taps the Drifter to use it, every turn forces a choice between attacking and tapping, and the tap symbol is what holds the card to one activation per turn no matter how much mana is open. This sits in the lineage of cheap repeatable tappers that predates the modern pinger: a one-mana ability that taxes the opponent's best creature every combat, paid for by the small frame and the self-tap. Modest alone, but a clean example of the cost-per-activation tapper template white returns to whenever it wants a defensive creature that earns its keep by saying no to one thing at a time.
