I did have more proliferate in there at one time, but Slowly took it out. Though I really want to find room for Inexorable Tide again. I'm also thinking of trying to fit lux cannon into it as well because it's just a mean card and with tezzeret and some proliferate it's that much better. As far as pillow fort strats go, I think cards like Ensnaring Bridge and Collective Restraint work rather well. You could also try Primal Surge with the ramp you have. I'm sure that could be a huge card with all the permanents you tend to have in that style of deck.
Intro: This Deck is obviously based on 5 color control with planeswalkers. It’s really a fun deck because of the shear amount of options that you have. The first thing you might notice is that there are no creatures except for the general. That was a style choice and I toyed with the idea of using just Phage in the deck for the bribery lovers of the EDH world but I figure my play group would catch on really quick. I find that I end up making my opponents scoop from having an ugly ultimate go off or killing them with general damage. In multiplayer I’ve also kicked many of my opponents threw the door ftw. Any Input you may have would be nice. I look at all my decks as a work in progress.
I have a very non-budget 5 color Planeswalker deck and one of the cards that is amazing in the deck is Maelstrom Nexus and for me since the only creature in my deck is the general Ward of Bones is also amazing. I also run Door to Nothingness. My deck is basically 5 color control with Lots of planeswalkers and removal. I run cards like Moat, Spirit of Resistance, Legacy Weapon, and Decimate is really good with a large play group. I run the main mana doublers and fixers like Mirari's Wake, Prismatic Omen, Mana Reflection, Chromatic Lantern. I'm not sure what you can afford, but all of those cards are really helpful in my deck and not all of those are that spendy. Just a few suggestions for ya.
