I would really fill out your 2cc counter section before including any 3cc counters besides exclude. In most cubes 2cc counter spells aren't really back breaking and they sorta self moderate in volume as they lose some of their usefulness in later turns. It's also just nice because the 3cc ones are really rarely splashable.
I played Vex in a constructed deck over rewind so I could win more matches against the Krarak-Clan Ironworks deck, so I don't feel like I should comment on Arcane Denial.
