energy gain and one cost attacks

[bug2]

hello,

if an energy gain is attached to an sp pokemon, will a one energy attack be reduced to a no cost attack?
eg, yanmega 4 and skill dive.

thanks

Q. If I have "Energy Gain" attached to one of my SP Pokemon, can I use an attack that only costs one energy without having any energy attached to that Pokemon?
A. Yes, as long as that attack costs one Colorless energy. If the attack costs only one non-colorless energy (i.e. one Fire Energy), then you would not be able to use that attack. (Jun 4, 2009 PUI Rules Team)
