The evasion-granting ETB is the whole reason this Griffin costs four mana instead of three. A plain 3/2 flyer would sit at the floor of white's common-rarity fliers; the enters trigger reframes it as a tempo enabler that hands flying to a ground creature for a single attack step. The interesting wrinkle is who benefits: point the trigger at a large, stalled beater and the four-mana body becomes a way to force through a chunk of damage the opponent could not have blocked a moment earlier. It rewards a deck that already wants to attack rather than one hunting for a durable engine, because the flying it grants lasts one turn and no longer. That narrow window is the constraint holding the card in check: it cannot bank evasion for later, cannot chain the effect across combats, and a 3/2 is fragile enough that trading it away carries a real cost. What it offers is a burst of reach that repeats only through blink effects and is otherwise a one-shot: the kind of glue that props up a white aggressive shell without ever headlining it.
