Once the game has been sufficiently controlled, the deck can win through various routes like with Isochron Scepter and Dramatic Reversal or through a more traditional win condition like Talrand, Sky Summoner and a host of counterspells to protect it
To proliferate, you choose any number of permanents and/or players, then give each another counter of each kind already there.) Creature Artifact - Soldier Robot Ral, Crackling Wit Whenever you cast a noncreature spell, put a loyalty counter on Ral
No More Lies Cavern of Souls is making people sleep on this spell a bit, I think
Mind Stone Ramp in control has always been taboo, except in the case of Mind Stone
Or if your deck is looking to draw more cards, by all means, add more card draw
I have a hard time imagining a game where the person that Ephemerates their Atraxa doesnt win
