A medium-speed format that grinds life totals down rather than racing them is the right home for a one-mana drain, and the pick band lands at P1P5 to P1P8 in any base-black deck, sliding earlier in WB or BG where the food tokens (Anchovy & Banana Pizza, Omni-Cheese Pizza) want a density of small triggers that add up to something real.
The flying is the part that earns the pick. The format's common ground stat lines top out at 2/3s and 3/2s, which means an evasive one-drop is a clock those bodies cannot answer in combat. That changes what the drain is worth: it starts as a single point on entry, but a flier that keeps connecting turns that one point into a recurring tax the opponent has no clean blocker for. The 1/1 does die to everything in range, so don't expect it to survive a removal spell. Stomped by the Foot, Grounded for Life, and an aura like Dimensional Exile all clear it. But spending one of those on a one-drop is a trade most black drafters are happy to force, and the entry value is already banked.
Where the card sharpens is as the cheapest equipment carrier in the format. Strap Novel Nunchaku to it and the evasion that ground decks already can't address becomes a genuine clock. WB and BG are the homes; mono-black-with-a-splash maindecks one without complaint. The failure case is the deck that wants the body to grind on the ground with no payoff attached, where the scry never compounds into a sacrifice or lifegain plan. Two is the ceiling before the chassis turns redundant.
