Seems a little light on removal, if you want to play fastish "wheel combo" you are way better off with nekusar as there are more options for magnifying the pain. NIV is generally better as a control commander, playing slower Counterspell game. Its ironic given that I am playing nekusar as a slow control, when theoretically I could do something similar and better with the combo version, but I am intentionally playing against that due to local meta (and personal taste). I would still say you would do well with a couple more boardwipes, like earthquake, and if you can get ftv: annihilation anywhere near msrp, rolling earthquake. Washout is another fantastic option. Not telling you to go full control, even without that you want some more reset buttons. Also, why no
forbid, it's probably the best Counterspell in commander, and it's not like you don't have the card draw to feed it.
