yeah though i could imagine a water/dragon starter, not weak to ice at all, but i forget it's strengths and weaknesses.
lets see if they did use dual starters with the most resistant types i think it would be water/dragon, grass/ghost, and fire/dark, but again don't remember all the strengths and weaknesses currently to know if those are even remotely good combos (cept maybe the water/dragon since i believe it takes normal damage from ice)
