The rate is a lie until the board fills in. A 1/3 trampler alone is a blank, and the design punishes casting it into an empty field: its power counts every creature you control, itself included, so the card does nothing until a swarm already exists to be tallied. Trample turns that count into a real clock, since the whole appeal is shoving a single big number past whatever chump waits to block. What makes this more than a top-heavy finisher is dash. A payoff creature like this historically committed permanently to a board it wanted kept intact, converting a whole developed turn into one attack and then leaving a fat target behind for the opponent's next sweeper or removal spell. Dash resolves the standoff by making the commitment temporary rather than the interaction impossible: it swings on arrival and returns to your hand at the beginning of the next end step, so the body is gone from the board on your opponent's turn, not immune to answers on yours. The window still exists (the dashed creature can be met with instant-speed removal before it connects, and the delayed return trigger can itself be responded to), but the honest trade is recurrence, not surprise. You redeploy each turn, recomputing that power against a board that keeps growing, without leaving a permanent target for a sorcery-speed wrath. Two settings and no middle: a haymaker once the width is there, a 1/3 with nothing to count on any turn it is not.
