I need to warn you that Beartic is not good. I tried it out myself, but its Ice STAB is not worth the loss of Water STAB. It's essentially a poor man's Kabutops.
Anybody have any luck completing the ladder challenge? I've been busy myself, but I'll try laddering tonight and see how far I can go xd. There are plenty of replacements for Kabutops, I believe, but nothing really fills Ludicolo's role. Maybe I'll just go all-physical with a Shell Smasher lol
