GSC OU Viability Ranking (credit to ZoroDark for format) Welcome to the GSC OU Viability Ranking! In case you're not familiar with the concept, we place Pokémon in certain ranks here, based on their impact on the tier as well as their general viability in the tier. This is an excellent help while teambuilding and it serves as a general outline of the tier. If you feel that a Pokémon is misplaced, feel free to make a post about it, after all that's what this thread is for. There's a couple of rules, though. First and foremost, make sure your arguments are clear. You may use usage statistics in your argument, but make sure your reasoning isn't entirely based on those. As always, be civil and don't get personal, otherwise you'll risk getting infracted. Pokémon are sorted into the respective categories based on how well they perform their roles. S Rank is reserved for Pokemon who are extremely threatening and impact the metagame in a major way. These Pokémon can either fulfill a variety of roles or are superlative in performing one task on a team. Snorlax Rank: Snorlax S: Zapdos Raikou A Rank Pokémon generally perform very well in the tier, but have some minor flaws that prevent them from fulfilling their roles consistently. Although threatening, they usually require a bit more team support than S-Rank Pokémon. A+ Cloyster Skarmory Exeggutor Vaporeon A Tyranitar Steelix Nidoking Gengar Miltank A- Starmie Forretress Suicune Machamp Umbreon Marowak Misdreavus B Rank Pokémon usually have some sort of major flaw that prevents them from being a more common presence in the tier. However, they still are able to perform their roles very well with proper team support. B+ Rhydon Heracross Dragonite B Smeargle Jolteon Espeon Porygon2 Blissey B- Meganium Tentacruel Quagsire Kangaskhan Golem Charizard C Rank: C Rank Pokémon have notable niches in the metagame, but usually require significant support. These Pokémon face competition for their roles from the higher ranked Pokémon, but can still find use. Clefable Ampharos Muk Houndoom Alakazam Not complete. Offer your inputs! D Rank Pokémon either have an extremely small niche in the tier, or are generally outclassed by higher-ranked Pokémon in a majority of circumstances. Not yet added, offer input if it's worthwhile having a D rank and if so, what it would contain.
