For pokemaster to answer, but feel free to answer too!
I have realised that a lot of people including me have fallen into a problem about which tag to use. Sometimes you just dont have a tag to put and are forced to use a random tag.
I think either you should be allowed to make tags like the meta on both pokebase and battle subway, or are allowed to have no tags at all. You can always put all required info on the description anyway. And why six tags ONLY?
eg: http://pokemondb.net/pokebase/88077/what-is-crasher-wake-doing - has the tag lucario. so...
I hope you get the point. >.<
