Weldfast Wingsmith

Evasion wired to a deck's natural tempo rather than to a cost you pay each turn. The 3/3 body is plain; the value lives in how the flying trigger folds attacks into a sequence you were already going to run. Cast an artifact, swing over the blockers, and the wings come free because you committed a permanent to the board anyway. The clause fires on any artifact entering, so a wave of cheap Servos, a Treasure, or a Clue all light it up, and it stacks each time within a turn even though flying does not improve past on-or-off. What pays for the effect is its impermanence: the flying evaporates at cleanup, so the Wingsmith blocks like a grounded 3/3 on the back foot and only carries damage on turns you are the one developing. That ties its aggression directly to the artifact density you build around it: in an artifact-heavy shell it becomes a recurring three-point clock that ignores ground stalls; strip the artifacts away and it reverts to a vanilla midrange body. The design is an honest exchange, evasion that costs no mana but demands you keep feeding the engine on the same turns you want to attack.
