Mizzet Gates
Mizzet Gates is my pet project and my favourite deck. This strange construction leverages the spellslinger nature of its commander Niv-Mizzet Supreme to delay and divert the game until you find 10 gates with different names and trigger Maze's End to win. It does this while conforming to Jegantha's companion rules - though it can often pull off a win without casting either Jegantha or Niv-Mizzet himself. It's suprisingly consistent (thanks in large part to low land-destruction capabilities in most low-powered casual groups) and warps the game in ways most other decks cannot. Added bonus - the manabase is incredibly budget friendly due to the fact that gates are simply not great lands.
