I know a lot of questions have been asked similar to this, but it looks like all of those are Ice beam and Avalanche, not Ice Beam and Blizzard. I don't want to have to breed this far in game, and I need an Ice move to cover the x4 grass weakness Swampert has, which one should I pick? I'm at the Lilycove Store right now, on Blizzard, and I'm wondering if I should buy it, or wait to find Ice Beam in the sunken ship?
