Godzfirefly: Great Job, almost nothing wrong with it, replace "it" with "the Defending Pokémon".
GlaceonFTW: Capitalize Defending, put the w/r clause for Nevermeltice in parenthesis, and capitalize both W and R, capitalize "energy", remove "This attack" from Snowstorm, put the period after the parenthesis, capitalize both W and R, you should probably increase W to +20, because 1. It has incredibly good attacks (possibly broken), and 2. Xatu had relatively poor attacks, only worked well on the Bench, and Metapod had only 70HP.

NidoPrince: Great Job, Replace "your" with "an", replace "would be" with "is", change the last sentence to "This has no effect if the attack has no base damage."
ensignmerlin: Excellent, why is it a Basic?, put a comma after "your", move "after doing damage" to the front of the sentence and remove the parenthesis, add "20 damage plus" before "20 more damage".

You opponent may not try to evolve that Pokémon again during the same turn", replace "a" with "any", capitalize Energy, add "cards" after "Energy", replace "him" with "it", replace "them" with a comma, replace "opponents" with "opponent's", capitalize Benched, capitalize Pokémon, add the é, do the same things the second sentence. add W, R, and RC, add Flavor Text.
