I like your take on Volo! I see you went all in on the copy theme.
I really like the use of
Adrix and Nev, Twincasters! I had never thought of using them because I was so focused on making sure that all my creatures didn't have overlapping creature types.
I would try and see if you can fit
Weaver of Currents into your deck. It gets busted with Volo making what is basically two Sol Rings. With your copy heavy strat you could get some crazy mana out of it.
Overall, I like how you built him! It was cool seeing how someone else interpreted Volo and his neat ability.
