Dewgong(sky) reads: (C)(C)(W)(W) Crushing Ice - 40+ This attack does 40 damage plus 10 more damage for each C Energy in the Defending Pokémon's Retreat Cost. Damage is calculated using the Defending Pokémon's Retreat Cost after applying effects to the Retreat Cost. Broken Ground Gym: The Retreat Cost for each player's Baby Pokemon and Basic Pokemon is increased by 1. Ariados: Pokemon Power; Gluey Slime As long as Ariados is in play, each player must pay an additional (C) energy to retreat his or her Active Pokemon. Gluey Slime can't make a player pay more than an additional (C) energy to retreat a Pokemon, even if there is more than 1 Ariados in play. When Dewgong vs. Magmar EX, does Dewgong's attack do 40(attack) + 20(Magmar's retreat cost) + 20(for the BGG and Ariados), then X2 because of Magmar EX's weakness? 40 + 20 + 20 = 80 80 x 2 = 160 damage Is that right? When the card says "(after applying effects to the Retreat Cost)", does that mean that I add damage for the BGG and Ariados? Now I changed the card to Dewgong from Skyridge vs. Magmar EX.
