Landfall in red-green has always pulled toward the same payoff: turn a fetch land or an extra land drop into a swing in combat math, and let trample carry the surplus past blockers. Here the trigger is a flat +2/+2 with no upper bound, so the body that starts as a 3/3 becomes whatever your land count this turn says it is. One land takes it to 5/5; a fetch land cracked on the same turn stacks two triggers and pushes it to 7/7, and every point above the blocker's toughness spills through. The card asks nothing exotic in return, which is the point: the deck it wants already plays lands aggressively for other reasons, so the buff is a tax-free rider on land drops you were making anyway. The vulnerability is structural rather than printed on the card. The pump lasts only until end of turn, so on a turn with no land drop it sits at a base 3/3 that trades with anything. The trigger cares about lands entering under your control, though, not about whose turn it is: an instant-speed land effect or a fetch land cracked during the opponent's combat can pump it defensively, so a well-timed land drop turns a 3/3 blocker into a 5/5 ambush. That timing flexibility is what keeps a no-ceiling pump interesting without the design needing a counter or a sacrifice clause to police it. What you get is a landfall-beater whose threat scales with how greedy your manabase is willing to be, its ceiling decided by the fetch lands and ramp around it rather than by anything written in its own text.
