At the beginning of combat on your turn, choose target nonland permanent you control. Until end of turn, it becomes a Vehicle artifact with base power and toughness each equal to its mana value, and it gains crew 2 and "Crash Land — Whenever this Vehicle deals damage, roll a six-sided die. If the result is equal to this Vehicle's mana value, sacrifice this Vehicle, then it deals that much damage to any target."
Cast Captain Rex Nebula, then each combat turn one of your high-mana-value noncreature permanents (an enchantment, artifact, or planeswalker) into a beefy attacking Vehicle whose stats equal its mana value. Crew it for 2, swing for big damage, and let Crash Land's die roll occasionally nuke a player or threat for extra reach. You win by stacking expensive permanents that double as evasive beaters and grinding incremental damage.
Raise your average noncreature mana value with impactful bombs (e.g., Smothering Tithe, big artifacts, planeswalkers) so animated Vehicles hit harder, and add evasion and protection like Reconnaissance and ward effects. Lean into recursion (Cloudstone Curio, Brought Back) to negate Crash Land sacrifices, and incorporate die-roll manipulation to control when Crash Land triggers. Tighten the mana base and add cheap, repeatable crew creatures so you never miss an attack step.
