Maybe Detention Sphere instead of O-Ring? Seems like you could get some more utility out of it for the same CMC, although the blue mana requirement may be an issue.

Well, with Harabaz Druid and Opulent Palace it really could work better than I first thought when I read your suggestion, gonna put it to the maybe's.

And now it's on the mainboard :)

I play dedicated control in modern and the only time allies give me trouble is when they la d a collected company. I think I suggested this for your humans deck too but double threats that will trigger all your etb effects at I start speed can just flip a match up. I would consider cutting Down sphere for them as control isn't where you want to be. You want to keep the paths as they will clear the way and keep the crazy bombs under control but you want to be jamming threats with 3 Mana not trying to control the board

I'll give it a try and switch the spheres for the company
