To be a proper counter you have to be able to switch in on any move from either poke and win the match-up, preferably being able to win with a layer of hazard up. It's up to Iss to decide, but that's the minimum requirements for a Poke to be classified as a counter.
Wobbyble, got any calcs for that?
240 SpA Life Orb Abra Hidden Power Fighting vs. 252 HP / 252+ SpD Eviolite Lickitung: 13-16 (46.42 - 57.14%) -- 12.11% chance to 2HKO
(13, 13, 13, 13, 13, 13, 13, 13, 13, 13, 13, 13, 13, 13, 13, 16)
Lickitung caps at 28 HP, so after switching in and taking a 2nd Hidden Power fighting, you're left at 2 HP assuming no max damage rolls. If there is any form of hazards on the field, then Lickitung loses. Meanwhile, even if there aren't hazards, you will have to spam Wish/Protect to get back to full health and all the while hoping for no Sdef drops from Psychic. Oh, and you have to carry Heal Bell to or you lose to Toxic.
