well yeah its a little slow, still theres always the choice scarf option.
ice is disgraceful as a typing, defensively it only resists itself and has like, 5 weaknesses uncluding to stealth rock and all that crap. really it should be resistant to water and grass or at least some resistances XD
as for balloon, i meant if you notice somethnig which is obviously choiced into a ground move you can bring it in. also with a balloon its immune to both ground and electric. also entry hazards and status moves dont pop the balloon, only direct attacks, so iuf you expect something to use a status (like some kind of tank, or a skarmory mainly)
