Esika's Chariot

Four mana that immediately makes eight power across three bodies, and none of it depends on the Vehicle attacking. That is the trick that separates this from every crew-cost creature-truck before it: the two Cats it drops on the way in already outvalue the mana, so the 4/4 body and its crew requirement become upside rather than a tax. If the Chariot never rolls out, you paid four for two 2/2s and a large artifact that four power's worth of anything can push into the red zone; if it does attack, the copy trigger duplicates a token you already control, and green almost always has a bigger one lying around than the base Cats. The design collapses two green strengths into a single card: token flooding and go-wide payoff, with the copy clause quietly rewarding any board that has grown past 2/2s. The Vehicle framing matters because it dodges sorcery-speed removal aimed at creatures until it crews and swings, and its legendary status is the only real brake on running it as a redundant four-of engine. The copy ability targets any token, not just its own Cats, so the ceiling scales with whatever else you are making: a treasure, a bigger beast, a token that carries a keyword. It reads as a curve-topper for a token deck and plays as a snowball that is hard to answer with one card.
