Commodore Guff help!

Hey EDH players!

I’m building a semi-budget [[Commodore Guff]] deck and need help tweaking the list. I think I’m heavy on planeswalkers and I’m wondering if I should add more counter spells… Any input is appreciated! I’m trying to stick to cards under $15. I’d love to add mana drain but it’s not in my budget right now. Thank you!
