Growlithe – Fire – HP70
Basic Pokemon
[C] Kick and Run: 10 damage. Switch this Pokemon with 1 of your Benched Pokemon.
[R][C] Flare: 20 damage.
Weakness: Water (x2)
Resistance: none
Retreat: 2
Okay... This is a stupid funny rogue deck idea: Growlithe's first attack is much like that of Donphan of old, where you attack and switch to a disruptive wall (Like Wobbuffet) or a prize denier (Robo Substitute - I wish that was still around :/).
At first, 10 damage isn't much - but with Volcanion-EX and Fighting Fury Belt, it can become even stronger! Even more, its potential Evolution, Arcanine, can take all the energy from your bench to deal the finishing damage:
Arcanine – Fire – HP130
Stage 1 – Evolves from Growlithe
Ability: Burning Road
Once during your turn (before your attack), when this Pokemon becomes your Active Pokemon from the Bench, you may move as many [R] Energy as you like from your Pokemon to this Pokemon.
[R][R][R][C] Scorching Breath: 150 damage. Arcanine can’t attack during your next turn.
Weakness: Water (x2)
Resistance: none
Retreat: 2
Now, would this be good enough to replace normal Volcanion builds? Probably not, but depending on the right cards coming out in future sets, this tactic could be worth scouting out later.
