I switch back and forth between a hammer tempest (which is complex on Deck) and a dual axe berserker (which is much simpler). Both are doable with the right controller template but the latter is significantly easier in my opinion.
I've been using SamCW's soulslike template since Steam release but there are a bunch of different ones out there. You can grab a bunch, try them out, and even modify them if you want. Good luck!
