I would suggest considering
Murmuring Mystic along with upping the amount of electromancers to 3 instead of just 2. Also Naban in your current deck really does not do anything except doubling
Viashino Pyromancer's ability and Naru Meha's who is on the sideboard. You could add exclusion mages to your deck or perhaps some omenspeakers if you wanted him to be useful.
Wizard lightning and
Wizard's retort should be mainboarded. While you should aim to have an electromancer on the board as often as you can these spells will cast less with any wizard on the board.
Thud also feels like a rather weird addition to the deck as your only good option in the deck is Niv-Mizzet and I would assume that you don't want to
fling him. All you other creatures are of low power and it is unlikely that adeliz will provide enough buffing to provide enough power for the
thud.
The main question I should ask for you is this. What are you aiming to do with your deck. Are you trying to run wizard tribal? Are you wanting to have a midrange deck that plays sweet spells with wizard flavoring? Or are you just wanting to abuse
firemind's research?
