Updraft

The combat trick that pays you back. Granting flying for a turn is a marginal effect on its own: it sneaks a blocker over a ground stall or pushes a point or two of evasive damage. What makes the card cohere is the delayed cantrip. The card draw is stapled not to resolution but to the following turn's upkeep, which defers the replacement instead of front-loading it. You spend two mana and a card now, get a body airborne now, and recover the card later, so the trick never costs you raw card economy even when the flying does nothing. The timing of the draw is the structural choice worth noticing. The spell resolves and goes to the graveyard immediately, leaving behind a delayed triggered ability that fires later regardless of what happens to the creature it pumped; a body that trades away in combat still earns you the card. Because the refund is separated from the cast, it arrives at a clean, unhurried moment, after the trick has already done its work in the current turn. It is the same instinct that later cantrip combat tricks would refine, packaging a fragile one-shot effect so the floor is "I drew a card and might have stolen some damage" rather than "I wasted a card on a creature that traded." Modest, but honestly built around its own constraint.
