Hello Delko and Mynism,
First I'd like to congrats you two for making this incredible hail team. In the previous posts people have been suggesting Hidden Power Fire Abomasnow, I can clearly understand where you both are going with this set and it should not be changed. You guys should try out
Choiced Scarf Terrakion instead of Conkeldurr, by this change revenge killing would be much easier. This poke also gives you insurance against Sand teams with CB Tyranitar (with predictions ofcourse) which can do massive damage to your team every time he switches in. Terrakion can become your another check to Sun teams where Conkeldurr fails. By this change you don't always have to fodder your team members just to revenge Dragonite and other big threats. Volcarona with weird Hidden Powers can also troll this team and Terrakion can take it down easily. I simply love your Tentacruel and Kyurem sets, well done. Again good job you guys for making this awesome team. Good Luck!
