Can you say very underrated? Nidoqueen is probably the most underrated stage
2 pokemon. Nidoqueen is just like a more powerful version of Nidoking (who is
too overrated, and stinks). One of the reasons why it is overrated though is
because of Mr.Mime, and I don't see why? For two energies (one grass and one
of your choice) it can hit Mr.Mime with 20 damage, and finish him off the
next turn. Second, Nidoqueen actually has a pretty good HP (the same as
Nidoking's)  and they both have the same weakness, and retreat, then,
Nidoqueen has mega punch which can do 50 damage (two grass energies and two
energies of your choice) which is pretty powerful considering you don't have
to discard any (this makes Nidoqueen very good against fire pokemon like
Ninetails because it can survive its hit, and kill it on the next turn
because it might be grass, but it's poison so it's weak against psychic
pokemon, and Ninetails will have to discard energy after its attack). Now I'm
not some poor card game player making this stuff up, I have won my city's
championship in pokemon cards and in one of my most powerful decks you'll
find Nidoqueen, with a pokemon that makes it invincible, it's Wigglytuff.
Nidoqueen is a power house and can kill almost any card, but lets say your
fighting a Kadabra, and he attacks first, you send out that Wigglytuff
because it has resistance, and to make sure you get Nidoqueen evolves
quickly, many Nidorans and Nidorinas are placed in the deck, which also helps
Wigglytuff do the wave and knock out its opponents.
