For the second mode, the Incubator token is chosen as Sunder the Gateway resolves. You can transform the Incubator token you just created or one you already controlled.

For the first mode, if the nontoken artifact or enchantment is an illegal target at the time Sunder the Gateway tries to resolve, it won't resolve and none of its effects will happen. You won't incubate.
