Niv-mizzet combo

[Birdbrain]

Niv-mizzet the firemind + mind unbound

Expensive, and slow. But effective. What could be a third card to add?

[Rcvines]

 {Curiosity},  {Ophidian Eye}, and  {Mind Over Matter} all infinite combo with niv firemind

[Elitehalo360]

{Niv-mizzet the firemind} + {mind unbound}

Expensive, and slow. But effective. What could be a third card to add?

{niv mizzet, dracoinious} works with firemind as well

[Iandtormentor]

omniscience + tamiyo's emblem + think twice + niv-mizzet, the firemind.
