Niv-Mizzet's Easy-to-follow 10 Guild Plan to Retake Ravnica (EDH / Commander)

Niv-Mizzet Reborn is a card that screamed out to me to be built around when he was spoiled, partly because of the story significance (HOLY SHIT, IT'S A 5 COLOUR NIV-MIZZET FIGHTING FOR THE FATE OF RAVNICA), and partly because the idea of drawing 3-4 cards and getting a 6/6 flyer out of the mix seems all kinds of up my Shadow Alley.

There's a bunch of avenues you can go down with a deck like this, but considering Niv-Mizzet's scheming nature (after all, him being alive at all is just part of a contingency plan), I figured that a control shell made the most sense. I'd be the first to admit that control isn't normally my style, so any suggestions people want to make just fire away!

We're trying to maintain as much of a "Guilds-Matter" subtheme as we can, so the signets fit great as a ramp/fixing package on 2. That's also why we're including the Maze's End alternate wincon, as well as for budget fixing purposes. For bonus flavour points, make your 10 basic lands either 1 of each Guild Kit basic, or the 5 land panorama of Ravnica being destroyed and 5 lands where Ravnica looks fine- the state things are in now, and the way we want them to be.

The deck has some number of cards of all 10 colour combinations, with a slight skew towards Azorius (the best control colours in general). In playtesting I've consistently drawn anywhere from 2-5 cards with this set up, but it could probably be optimized for some more efficiency. One place it may be worth cutting is Fist of Suns/Conjurer's Closet, but the former makes it infinitely easier to cast some of our more intensive-cost spells, while the latter let's us repeatedly use Niv's ability, so I'm not sure.

This deck is far from competitive, but it's an absolute blast to play, and nothing quite feels like seeing a massive chunk of your deck and cherry picking the best fits for your current situation.

As always, any and all suggestions are much appreciated!
