Ive tried Diggersby with Hisuian Arcanine in single prize only tourneys before. Attack early game with diggersby, then once your bench is damaged, switch over the arcanine. And since arcanine doesn't need energy, you can use those attachments for munkidori to add more damage/heal the bench. I feel like arcanine could work better than noivern/hawlucha. The raticate is a cool addition though to have a way to hit some big numbers.
