The math is the whole point, and the math is punishing to the wrong side. A 3/1 for three trades badly with almost anything on turn three, but the landfall trigger converts every land drop into a 5/3 trampler for a turn, and any land that fetches a second land stacks two triggers on one attack for a 7/5, all of it running over blockers on the way down. That is the design compact: the toughness never grows on the base body, so it dies to a single ping or a chump-and-trade the moment a land is not entering, but connect on a turn with two lands and the trample keyword makes the whole bonus land as damage rather than getting soaked by a token. It rewards the deck built to keep dropping lands rather than the one that curves out and stops, which is why it lives alongside additional-land-drop effects and land-recursion that keep triggers coming past the point a normal deck runs dry. The 1 toughness is not a flaw to be played around so much as the reason the aggression stays cheap: a creature that hit this hard on a durable body would cost more or care about more. Here the fragility is the price, paid up front, for an attacker whose ceiling on the right turn is genuinely absurd.
