From my playtest, it does better than I tought.

I've always been a fan of gimmick decks with strange win conditions which is why I am so fond of Maze's End . The deck definitely can win some games. Reliability is my concern. Do you have any suggestions?

The worst nightmare of this is Burning Earth :D

Anyway, I think that the Prophet of Kruphix actually makes Maze's End a lot more playable since you can (kind of) use it the turn you play it. And I think the Urban Evolution is also very crucial, maybe you should try and add a fourth.

I definitely do want a fourth Urban Evolution . Should I cut one Prophet of Kruphix for it? Or something else?

I'd think that the two Jaces should be either moved to the sideboard or cut out and replaced by one each of Urban Evolution and a Simic Guildgate (or instead of the latter maybe a lower cost disruption spell or another Prophet of Kruphix ).

The thing with him is that you can't really protect him, except with Fog (the other fog effects don't work with PWs), and if you use his +1, that's basically cycling him, while Urban Evolution gives you 3 cards. He can serve as an alternate win condition against control, but otherwise I'm really not sure about him.

Also would actually put in a bit more green sources since you're so dependant on green. Maybe remove one of the Maze's End and put in another Simic Guildgate .

Thanks for the suggestions! I have moved the Jaces to the sideboard. I like having multiple win conditions in my opening deck, but more often then not I don't play him first round anyway.

I've also made the suggested land swaps. I've never had a problem getting the green or blue that I need, but keeping the manabase reliable is good.

Am I crazy to try and play this deck semi-competitively? And what do you think of Riot Control ?

I like Riot Control , why is it not in there? It gains you life, which is nice.

Have you considered any of the cards that interact with having a crap ton of gates? the only one worth it is Saruli Gatekeepers , in my opinion, again for the life gain. That can be necessary when you've got nothing to defend yourself with.

Maybe Nightveil Specter ? He's super cool with a five color deck, as you can assuredly play anything and everything he exiles.

A cool idea a friend of mine told me about is Possibility Storm . In a deck like this, it could (arguably) work to your favor. You're screwing up their strategy while Fog ing it up still. Anytime you cast a fog spell, it'll turn into another fog spell, so you won't have any trouble stalling like that. Plus your Into the Wilds interaction still happens, and since you're only running two creatures, having either of them out is nice. It's just a silly thing I'd really like to see happen someday. Haha. Nobody runs it, but it's such an interesting card.

Anyways, I don't think this deck would ever make it competitively. It's just too darn slow. But just have fun with it! Even if you take it to FNM and lose, you should run it for the lulz when you actually BEAT somebody with it.

What should I take out for Saruli Gatekeepers ? I really like where the deck is now, but life gain and a decent blocker are always welcomed in a deck like this.
