This is my first EDH deck I'm putting together. Suggestions are of course welcome.

My playgroup is casual with fun brews going on. None of us play cruel control or instant win combos.

I am a control/politics player at heart who loves having all the answers.

My main win condition is to control the board until I can get a massive Maro snuck through with a Rogue's Passage. If all else fails, drawing myself out with Laboratory Maniac on the field is possible.

Obviously the main goal is to get a maro on the field and then drop Prime Speaker Zegana. From there, bouncing Zegana with Riptide Laboratory or Erratic Portal (or even Capsize if needed) and dropping her again gets out of hand pretty quickly. With any luck at all you'll draw some way to eliminate your hand size and you'll be set.

Another big goal is to get Kruphix, God of Horizons online and start amassing mana. The main point is to abuse Spell Burst and Capsize with buyback. Alternatively, you can really make a Mindshrieker scary, or make someone draw their deck with Stroke of Genius (Yes, I know I could include cards like Skyscribing but I consider that too much of an "instant win.") Other good mana sinks are Memnarch and Staff of Domination.

That's the gist of it. There is a wizard subtheme for whatever. The rest is control, protection and tutors. Here are some interactions off the top of my head:

Crucible of Worlds and Constant Mists for recurring fog, or throw in an Exploration and a Glacial Chasm for pillow fort goodness. It also plays nicely with Ghost Quarter.

Silent Arbiter and Maze of Ith also keeps you from being run over, and it also lets you play wonderful politics. It can also be a good way to finish someone once you have dozens of cards in hand and a Maro on the board. Suit it up with a Rancor and swing in for close to lethal.

There are a lot of tutors to help assemble one of the above pillow fort scenarios (or just get the answer you need at the time.) You can chain tutors fairly easily because of transmute. A Mystical Tutor can grab a Muddle the Mixture, which can be a counterspell if needed. An Expedition Map can grab a Tolaria West which can transmute for a Summoner's Pact. A Drift of Phantasms can transmute for a Crucible of Worlds or for a Fabricate to grab a different needed artifact, like Psychosis Crawler or Duplicant.

Other than all that, most everything is self explanatory: either it's good with card draw or just value/removal. I have not thought of everything and I haven't built this deck yet. I'd love some suggestions, but I am going to throw this together as is and do some actual playtesting as well.
