Icecave Crasher

A 4/4 trampler that grows only when a land enters, which ties every point of extra power to the one resource the deck was already spending. The pump is honest by construction: it fires on the land drop that happens anyway, so a stock body scales with mana investment rather than a free trigger. The value is entirely front-loaded into the attack step. Crack a fetch, a Ravnica-style bounce land, or a second land off a ramp spell before combat, and each entry stacks another temporary point of power, so a body that started at 4 pushes through a wall of chump blockers for a number the defending player did not plan for. Nothing about the effect asks you to build differently: a deck that floods lands early is already the deck that wants this, and trample is what converts those fleeting points into damage the blocker cannot eat. The ceiling depends on how many lands hit in a single turn, which keeps the payoff tethered to genuine ramp rather than raw card advantage. It is a plain floor with a spiky roof, a landfall aggro piece that rewards a curve built around cracking lands mid-combat and does nothing special in a hand that plays one land a turn and passes.
