Lumbering Worldwagon

Ramp and payoff folded into a single body. Green has always paid for basics to reach the battlefield: Rampant Growth, Explosive Vegetation, Sakura-Tribe Elder. What this Vehicle does is loop that fetch into the attack step, so every swing thickens the manabase while making the attacker bigger, because a characteristic-defining ability sets its power to the number of lands you control (including the one you just fetched). The two halves feed each other: the search that accelerates you also raises the number that decides how hard it hits. The crew requirement pays for the deal. At crew 4 this is not a turn-three attacker in a vacuum; it demands a board committed enough to tap four power, which means the ramp shell has usually done some of its work before the Worldwagon starts amplifying it. Because the search fires on enter as well as on attack, an uncrewed copy still functions as a fixing enter-the-battlefield ramp piece, a floor beneath the whole plan when the board cannot crew it. The tutor is basic-lands-only and enters tapped, so it fixes and accelerates without opening nonbasic tricks; the shuffle thins the deck rather than building a value engine. A Vehicle that wants a wide green board is an odd bird, and the artifact type line lets it sidestep most of the creature and enchantment removal that green ramp normally plays around.
