Look at the target line on the second ability: it pumps artifact creatures specifically, not any attacker red could buff. That restriction announces her purpose. She is a build-around for a deck full of metal, where the Thopter she brings along on entry is both immediate evasion and the first body the pump can point at. The third ability turns a go-wide artifact board into reach: sacrificing a spare token (or a dead artifact you were done with anyway) to push a blocker out of the way converts board presence into damage, which is exactly what an aggressive deck of small artifact bodies tends to lack. Three lines of text at three mana reads as busy, but they resolve into one coherent job: she makes an artifact swarm hit harder and connect more reliably, and she costs the deck nothing to include because she arrives as an artifact-matters payoff with a body and a flier attached. The friction is that none of it does much outside that shell. The pump wants artifact creatures to point at, and the sacrifice cost wants artifacts you can afford to lose; strip those away and the abilities have nothing to feed on, leaving a modest 2/2 and a single token. She is an engine piece for artifact aggro, not a generically good midrange creature, and the design is honest about which deck it was built to reward.
