Hi, the 1 st Edition of Gym challenge came out Friday at Supr Software in
Austin, TX.

I got a Blaine's Charizard. Roaring Flames attack  F 20+ reads : Discard all
(fighting symbol ? ) energy cards attached to Blaine's Charizard. If all
Energy cards attached to B's Charizard provides 2 (fire symbol) Energy,
discard all of them. This attack does 20 damage plus 20 more damage for each
(fire symbol) Energy discarded in this way.

Is the fighting energy a misprint?

Thanks for looking into it.

                                                 Sincerely,

Absolutely.  Due to 1 too many Maple Bars being consumed up in Washington, they let a couple of major errors pass by.

#1 is the Charizard that you mentioned about.  It should be fire, not fighting energy

#2 is the Rocket's Minefield Gym, where a "2" was left out before the phrase "damage counters"

WotC has issued official errata fixing these cards.
