You know we have nothing better to do with our time when we're using a page of viability rankings on the (lack of) merits of Slaking. can we pull a page from RU and blacklist Slaking plz
Anyways, to make this brief. Yes, Slaking is powerful. Yes, it can kill things. Guess what else with normal typing can hit hard. Oh, idk, maybe Ursaring, Swellow, Tauros, Dodrio, Bouffallant, Kangaskhan, and Zangoose, all of which don't have the very significant flaw of giving your opponent free turns in any scenario. All of these, even if they cannot all outdamage Slaking in one turn, aren't complete garbage because they aren't allowing your opponent the 100% free opportunity to sweep you, and even if they do lack sweepers(which I mean there are a shit-ton of good sweepers right now, most of which are common, and especially smashpass is on the rise), they can just bring in powerful attackers such as Sawk and voila, get either a free kill or at the very least force you into a terrible scenario because you have given them a free opportunity to bring said mon into play. The very few times a Slaking will actually work well vs someone who actually knows what they're doing isn't worth the very many times it won't
Also, no offense, and I hate to be the elitest, but by the fact that you're arguing a pokemon any competent experienced player knows is garbage, your lack of knowledge of the NU metagame is blatant. I'd suggest not basing a pokemon's viability on something that isn't probably matches vs low rank NU ladder players that think Gurdurr is OP and use whatever garbage set some bad poketuber used recently.
