>>13390657no way, poison and ice are the worst. ice typed moves are some of the best but ice typing on a pokemon is baaad.
poison is weak to ground and psychic and only has one type which it hits for super effective. additionally the best move in the game, toxic, is learnable by all pokemon. poison is my favorite type but it is definitely worse than grass or bug. it is occasionally a good defensive complement and access to toxic spikes/ability to absorb toxic spikes are the only reason poison ever shows up.
gengar is possibly the most used poison type pokemon of all time and the only real benefit it gets from that typing is the ability to use black sludge. (at the cost of a weakness to psychic)
