Tidus, Blitzball Star

Two triggers, and they want two different decks. Tapping a defender on the swing is the tempo half: it fires on attack declaration, so it clears the blocker before combat math even begins, letting a 2/1 that would trade down instead poke in unopposed and add to a widening board. Growing off artifacts entering is the other half, and it points somewhere else entirely, since it ignores combat outright and rewards a shell built on tokens, cheap equipment, and recurring metal rather than the spells-and-creatures cadence Azorius usually runs. That split is the design problem. A clean tempo build attacks well but never grows the body; an artifact-dense build grows the body fast but still has to get it through the red zone to cash those counters into the tap-and-swing plan. The card asks for both halves of a deck that do not naturally share a list, which is a sharper deckbuilding riddle than a three-drop 2/1 usually poses. Treat it as a payoff built on solving the artifact-cadence question first, then leaning on the attack trigger to keep the swelling body unblocked, not as a standalone aggressive creature that happens to have upside stapled on.
