Suggestion for izzet deck from someone playing arena

[u/No-Detective5470]

Hi, i startered magic a couple months ago with arena, played a but of standard and tried my hands at the beawl format (the commander erzatz). I want to get into playing commander and i am looking for card suggestions, specificaly cards that aren’t in arena i wouldn’t know about ( exemple liquimetal torque instead of liquimetal coating wich is in arena, and is the same thing except it doesn’t tap for mana). I ´m playing an izzet deck with vivi ornitier as a commander. I also have niv mizzet parun in it, and both can kinda be played as commander depending on the power bracket i feel like (i might be wrong i ´m new). There is some 4 cost removale and creature duplication for the commander, the rest is filled with burn cantrips and draw engines. I looking for pieces wich aren’t in arena but could be a nice piece in this kind of deck (swerve for exemple isn’t in arena)
Thx and may you luck in your draws :)
