Approved by Molk. Idea stolen from NU. Op stolen from OU.
As we all know the metagame changes constantly. People come up with new revolutionary sets that get popularized very quickly and become the standard, threats are banned and overall usage drops. The purpose of this thread is to remember these once metagame-defining Pokemon of the 5th Generation, and elaborate and discover more reasons why they dropped in usage, why they were so effective, and why the metagame at the time allowed them to be so good. I will be usually weekly posting a new Pokemon that we can discuss. I will try to make the options as interesting as possible, and make sure we have variety for all parts of the BW1 and BW2 metagame.
Molk came up with the idea of doing two Pokemon per week on irc so here we got our first two Pokemon of discussion for now.
Drapion was at one point one of the biggest offensive threats in RU. It's Swords Dance + Taunt set absolutely ripped through defensive teams for a large majority of BW1, it has quite a bit of versatility, and was in general a very good Pokemon, reaching 4th in the usage stats at one point iirc. However, Drapion now finds itself barely holding on, seeing itself as 50th in usage - now its considered just too weak to do anything, and not bulky enough to consistently perform, and people don't even mention it when they mention Pursuit. What changes occurred to make Drapion considered so mediocre in the metagame?
Crawdaunt, on the other hand, has never exactly been lacking in power, and was a huge threat in the early stages of BW2 (it got Superpower) as result of this, especially with its threatening Dragon Dance set thanks to its strong dual STAB combo. Even though Slowking is everywhere now which would seem good, Crawdaunt isn't really made out to be much of a threat, often completely dismissed for its lowish speed. What changes to the metagame resulted in Crawdaunt's low usage?
