Lifecraft Engine

Vehicles have always been awkward tribal citizens: noncreature until crewed, they slide right off any lord effect, and a fleet of cars and mechs has no obvious type to rally behind. The type-grafting clause here solves that from both ends. On entry it stamps a chosen creature type onto your Vehicle creatures, meaning the ones that are actually crewed or animated, and then hands a +1/+1 anthem to everything of that type. The natural play is to name whatever tribe your fleshy creatures already share, so a crewed Vehicle joins the ranks as a genuine member, swinging and picking up the buff alongside your existing threats. The anthem pointedly excludes the Engine itself, keeping the reward aimed outward rather than fattening a body that has to be crewed to attack anyway. Its own Crew 3 is the built-in tension: the same creatures that move it are the ones getting bigger, so it taxes your board and rewards widening it in the same breath. The choice locks on entry, which is the real deckbuilding cost hiding behind a modest four-power frame; you commit to a tribe before the game tells you which one it wants. What makes it worth studying is the bridge it builds, granting Vehicle-heavy strategies access to the whole library of creature-type-matters payoffs, but only for Vehicles that are on the battlefield as creatures, never for the ones sitting inert between crew steps.
