~ Icicle Drop
~ Stone Edge
~ Substitute
~ Claw Sharpen
Substitute first for general protection, use Claw sharpen to get an atack and accuracy raise and you can pick your move whitout fear of a miss thanks to claw sharpen, and if things get ugly you can grab a boost from liechi(saved this bear's life many times)
what do you think?
Swords Dance will be the better option. The Damage output is tremendously higher.
