Least popular type

[Iveechan]

I never consider Breloom as grass types... as it relies on brick break and return/HP whatever to dish out damage... i mean giga draining Breloom = a dead mushroom. Though it is technically a grass type i don't consider it as one. The only grass move it should ever learn is spore (who doesn't want spore? ^_^)

Even if you don't consider Breloom a grass type, that doesn't change the fact that it is one, and carries most of the weaknesses (ice, fire, poison, and double flying), not to mention the added psychic weakness.

dragon and ghost maybe rare but very very commonly used. All of the dragons are in the usable realm, and this is true for ghost as well. Those annoying little bugger...

I meant to the kind of player who doesn't read guides or goes on forums... not many people who don't play seriosuly will know that you get Flygon from trapinch or Nincada's little evolution secret. I know dragons and ghosts are used a ton by "real" players.
