The problem with Swords Dance Cobalion is, what move are you skipping to add Hp Ice? Losing Stone Edge means Zapdos/Chandelure set up on you, while losing Iron Head/X-Scissor means bulky Psychic types laugh at you. I usually like running CC/Stone Edge/Iron Head as that coverage is only 100% walled by Slowbro, Qwilfish and somewhat Gligar (which you can beat with a bit of luck on your side). I'm not saying Hp Ice is bad, but Cobalion is only getting past 1 of its counters with Hp Ice, which is something that pretty much sucks because it still gets horribly walled...
Very true. And thats cobalions biggest flaw is its coverage. Stone Edge for zapdos and other flyers, X-scissor for Slowbro and mew, and iron head for idk just another decent STAB. Personally I run the set Close Combat, Stone Edge, HP ice. It gets through most of its counters but bulky psychics. And being able to get passed gligar is a huge plus since its now the most commonly used wall this round. Pairing it with a heracross might actually be a good idea since gligar's job responsibility will be need to counter the duo only to be brought down by a random HP ice giving heracross a free chance to sweep
EDIT: Just found another legit reason for HP Ice. It 2HKOs tangrowth and catches Flygon on the switch or just straight out KOs flygon if its locked into outrage or not Scarfed EQ. Something close combat cannot do alone
