From the info given, you have two wizards and are planning on making a third, so there wouldn't really be much of a need to leave anyone out.
If you're asking what your next three wizards should be after that Ice (and thus leaving one wizard out), that's still not something I could answer very well. But if I had to guess, from the look of it you're a fan of the tankier schools, so you would probably also like Life. You might not like how fragile Storm is. But then again, this is a guess; you might actually like Storm and opt to "leave out" a wizard of a different school. Just don't worry about making this decision until you're ready to make your 6th and final wizard.
I have a balance and a death. I am planning to make an ice.
Happy Holidays!
