In terms of playability in standard, you'd probably just have to ban Vivi. He does so much on his own that there's no reason to run any other izzet deck unless you want to run a budget deck. Outside of that, the rest of the components are there, though maybe the deck might want some more tapped artifact lands. What I find interesting is that Cavern of Souls and Secluded Courtyard let you play whatever robots you want, and we have more than enough one-drops (including a Springleaf Drum-bot) to allow for easy ways to dump your hand out.
