Dune Drifter

The X sits in the mana cost, not on an activated ability, which is the whole trick to reading this card. You pay for the reanimation up front, at cast, and the size of what you can return is locked the moment the Vehicle resolves. Spend nothing on X and it returns a zero-drop, effectively a bear-sized 3/3 chassis that recurs a mana rock or a token maker; sink real mana in and the same enter trigger hauls back something expensive, but you have paid twice, once for the X and once for the Vehicle itself. That front-loaded cost is what keeps a two-color reanimation body from becoming a repeatable engine: it is a single beat, priced by how greedy you want to be. The Vehicle typing is the other half of the design. Because the Drifter counts as a creature only while crewed, it can sit on the board as a bare artifact and slip past removal that only reads creatures. It also produces its own crew fuel: a returned creature can tap toward the crew cost even under summoning sickness, since crewing is not attacking, so the reanimated body immediately animates the chassis. What the animated Vehicle cannot do is swing the turn it enters, absent haste; a Vehicle that becomes a creature the turn it arrives is still summoning sick. Reanimation that flexes on curve and hides behind artifact status when it is not needed: modest ceiling, unusually clean floor.
