>>12046577>and the types besides dragon>BESIDES dragonYeah, go there and try to slay dragons without Ice and see if something happens.
See? Without Ice, the game would be ridiculously unbalanced.
And none of those three types have any weaknesses in common, so Ice STAB can nail Flying, Ground and Grass types pokes on it's own, which can be pretty useful.
My theory is that no one really uses Ice because of the shallow movepools and bad distributed stats of Ice type pokes.
Let's say we took Cryogonal, and swapped it's special attack with it's special defense, and added Flamethrower, Nasty Plot and Thunderbolt/Thunder to it's movepool.
I'm not sure if it'd be OU, but it'd be a quite good poke. In OU it'd have a hard time because of Scizor and SR.
If I could give it Magic Guard as well it'd be OU, but giving Magic Guard and those moves to pretty much anything would make it work in OU.
