This isnt the only way you can build Muldrotha, however
It would make more sense to have more tutors for artifacts in decks instead, since a tutor for artifacts can search for both Vehicles as well as other types of artifacts (hint: Boommobile can combo off with two other artifacts Cogwork Assembler and Panharmonicon)
If it becomes night, Hound Tamer's Nightbound side, Untamed Pup improves its value considerably, growing it into a 4/4 and providing all other wolves and werewolves with trample while retaining its Daybound abilities
Still, if you have team-wide trample, this card gets obscene very quickly
