You may target a spell that can’t be countered. When Mystic Genesis resolves, the target spell will be unaffected, but you’ll still get an Ooze token.

If the target spell is an illegal target when Mystic Genesis tries to resolve, Mystic Genesis won’t resolve and none of its effects will happen. You won’t get an Ooze token.
