PJ/EQ Nidos

I don't use them, they are weak vs Rhydon, Vaporeon, Gyarados, Blissey, Snorlax, Donphan, Espeon, and there are no defenders that are weak to poison.
Dragonite resist earthquake and Tyranitar resists poison and the royal family doesn't resist their moves.

Man the Nidos were my first high CP acquisitions. Back then you saw the random Wigglytuff in gyms. To be honest, now I just don't know what they can do well in the current meta. It's awesome that he double resists poison...then you realize poinson mons also resist poison which is his only stab quick move. If he has a niche I haven't found it yet.

I used to use them against Arcanine when they were still relevant defenders (high CP, even higher than vaporeon I think). Earthquake really destroys arcanine, but Poison jab does not do super effective damage.

I guess it's a poor man's muk if you get the double poison variant. It's not as strong but way more common than grimer.

lets hope they introduce abilities into the game.

I've used the nidos in battle and they performed better than expected.

I make myself use random mons in battle.
I star only my A moveset mons, and sort my "favorite"
I'll then choose what my max cp for prestige, then pic the next 6 mons no matter what. (OK unless the matchup is terrible.) This makes me use lots of my mons. It is really fun.

For that particular moveset I use them against any Flareon and any Jolteon. I have several 1700-1900CP Nidoking and Nidoqueens with interesting movesets. As long as they can resist the attack, I try to mix them in to make things interesting and give them use.

I have 95%iv NidoKing with PK/EQ power up to lv 30 and then use candy for leveling.

Nidoran god for leveling. LoL...

Every time I've used them, I've been like "Damnit, why did I even bother? That sucked!"
