Quote from Guild McCommunist »I think you need a way to prevent card drawing. If they have a commander with some form of inherent card advantage (like Azami for instance) then they can just spam draws until you can't cope with them anymore. Notion Thief seems like the perfect answer. Alternatively, Omen Machine seems good. Mill anything relevant from your opponents top deck and you can even mill yourself for some great value.
The other issue is opening hands. It's not like modern where you can pick them apart with Thoughtseizes and often weather out the storm, sometimes they just have the card to destroy you in their hand. Myojin of Night's Reach and Cabal Conditioning offer mass discard that hits all of your opponents to get them empty handed, at which point you can control their draws. I've even had success with Mind Twist just to put a control player out of the game.
I'm mostly looking at your actual version and not the budgetless one so sorry for some redundant suggestions.
