regardless of how unrelyable golducks attack is, if you have a couple gyarados out, it wont matter ^^, but near the beginning of the game it can be a nuisance..unless you pull a mentor with Mind play on turn 2 or something.. i had this deck before.. and people used windstorm alot more than they played their own stadiums, or played it before their own stadiums, so golducks power was rendered useless *shrug*
as well as gyarados'.. fearow worked alot better and made the game faster for me but, you may want to play it out a couple times each way, to see what works for you
