Welkin Guide

Five mana for a 2/2 flier is a price that only pays off if the entry trigger carries the card, and the design hands the whole load to that trigger: +2/+2 and flying to a single target on arrival. The mandatory targeting points the card at two distinct jobs. The tempo read turns a stranded ground creature into a temporarily evasive 2/2-bigger attacker, sneaking damage past a clogged board for a turn. The closer read is more honest: if you already have a creature large enough to end the game, granting it flying for one swing makes the body that tags along beside it incidental rather than the point. The until-end-of-turn clause is what fixes the effect as a one-shot rather than durable evasion, the line that separates it from the aura versions of this same idea: a creature wearing a flight-granting aura stays airborne, while this buys a single sky-bound attack and then leaves a flier of its own behind. The Cleric on the type line nods toward life-gain and healer shells where bodies like this tend to congregate, though the targeting itself is color-blind. There is no whiff floor: the trigger is mandatory and must find a target, so on an empty board it points at itself and enters as a 4/4 flier for the turn. The ceiling is a stalled race cracked open in one attack step; the floor is still a self-pumped beater, never a vanilla one.
