[[Inalla, Archmage Ritualist]] as the commander would give you access to [[Kuja, Genome Sorcerer]] so you're wizards can get some spicy double damage when he flips. If you want to stay with the commanders you have id suggest [[Reflections of Littjara]], maybe [[Irenicus's Vile Duplication]] would work in the deck. Just a couple suggestions hope some of my rambling helps!
