At the time of writing, theres only one real competitive deck that relies on Vehicles, and thats Greasefang in Pioneer
This is dangerously good, better than Young Pyromancer good, when you have silly mana production courtesy of Cradle or Crytolith Rites etc but it is much more on the fair to unimpressive side without
Dragons of Tarkir gave us five newcomers (Dragonlord Silumgar, Dragonlord Atarka, etc.), Core Set 2019 gave us retrains of the originals (Arcades, the Strategist, Nicol Bolas, the Ravager), Strixhaven added five more as the namesakes of the different schools (Tanazir Quandrix, Beledros Witherbloom, etc.), and the five metal dragons from Baldur's Gate were also given the double creature type (Ancient Bronze Dragon, Ancient Copper Dragon, etc.)
This can be used in politics regarding other players, its a gate that can be fetched with other cards, and it works wonders with mechanics like dethrone
Remember how I said that there are few-to-no completely bulk mythic rares these days
