For a long time I've found Hail to be a really underwhelming force in UU, with only Hail Stall being a viable form of usage for Hail. I decided it was time for me to try and make a viable offensive Hail team for myself when I saw a really cool Choice Band Abomasnow set on someone else's RMT. I've been a long time fan of Trick Room in UU, as it can be a very potent force if used correctly, so I thought I'd try to put these two offensive styles together. I manage to make this team pretty resistant to Hail damage, only Kingdra actively loses health from being in on Hail. This team is far from perfect but I've had a ton of fun using it and would love any advice I can get on making it better.
