Depala, Pilot Exemplar

The card that asked Vehicles to be a tribe before they had the depth to be one. Two anthems stacked into a single body: Dwarves grow, and Vehicles grow but only while crewed and animated, a clause that ties the buff to the exact window in which a Vehicle can be attacked into or blocked. The third ability is the tell that this is a tribal payoff rather than a generic lord: a tap-triggered, pay-X dig that filters the top of your library down to Dwarves and Vehicles, scaling card advantage with available mana while everything else gets buried on the bottom in random order. The clever part is that the trigger keys off her becoming tapped, not off attacking, so the natural way to fuel the engine is the same act that powers the deck: tap her to crew one of the very Vehicles she pumps. That single activation both animates a Vehicle worth pumping and reveals the next batch of Dwarves and Vehicles to feed it, and she never has to leave home to do it. That crew-and-refuel loop was an honest attempt to hand a narrow creature-type-plus-artifact theme its own anthem-and-engine in one card, at a moment when the supporting pieces (Dwarves as a real tribe, crewable Vehicles as a deck) were too thin to reward a lord this ambitious. She heads a small lineage of dual-tribal commanders built to reward two card categories that rarely overlap, with a selection valve that only pays out once you have committed to both.
