Also, base set Charizard
and Stormfront Charizard
have the exact same moves, PokéBody, HP, and WRRC. Yet base set Charizard's Fire Spin says "Discard two Energy cards
attached to Charizard in order to use this attack
", whereas Stormfront Charizard's says "Discard two Energy attached to Charizard." Why is it that you have to discard Energy attached to the base set Charizard but not the Stormfront Charizard if the two Charizard cards are meant to be identical (with one being a reprint of the other)? In other words, how is one a cost and how is one an effect?
I don't understand... :/
