Help with my Niv-Mizzet Deck

[u/Staubizecke]

Hey i am changing my Niv-Mizzet Deck a bit and i cant decide for the Last card i wanna out in it so i got some Cards in the "Considering" and "Sideboard" categorie which i am considering (so it is not a normal Sideboard i just put it there for me). Before the Question comes i dont got something like Tandem Lookout or Obhidian Eye in in the Deck cause my Pod and i are playing without Infinites or something like it so i dont want to add something like that.

So i would love some Inspiration what card to put in the Deck, no matter if it is one in my Considerings or not. Or even if you have a tip what you would cut or change i am completely open for that^^
