Thornwind Faeries

The repeatable tap-for-one-damage ability is a design tool that usually lived on a sturdy artifact body or a ground-bound blue wizard (the "Tim" lineage running back to Prodigal Sorcerer, where the nickname comes from); bolting it onto a 1/1 flier swaps board control for evasive inevitability. Once summoning sickness wears off, it can pick off a fresh one-toughness creature and then fire again every turn it survives, grinding a slow game to dust. The catch is that surviving is the hard part: the same toughness that buys the cheap pinger makes it a casualty of any burn spell, and the ability protects nothing. Flying is the quiet upgrade over a grounded pinger, but with no vigilance it forces a referendum every turn rather than removing one. Send it into the air and it chips a single point of damage but taps down, locking out the ping until it untaps; keep it home and it fires the gun but never attacks. One body, one tap, two jobs that cannot both happen in a turn: that is the whole tension. It wins grindy games single-handedly and dies to a stiff breeze in fast ones, which is why a one-toughness source of repeatable damage has stayed a recurring design problem rather than a solved one. The math is honest about what you are buying: not a clock, but a slow lever you have to keep alive to pull.
