Oh yes, crewing tapped vehicles is great. It always think of it as turning on the car but it is out of gas :)

One good place to look for dwarf deck (or any deck) on arena is the MTGA arena zone website. Here is a link to a search for Depala decks: https://mtgazone.com/deck/depala-pilot-exemplar-historic-brawl-deck/

Oh sorry I missed your comment, I know it’s been a while, but if you are still interested let me know and I can send you some of my deck lists that I use. I have a few on arena too.

Well I personally like that decision, besides there is only so much design space for Planeswalkers.
