Fire Dogs (and a Dunsparce)- Eon

[Dek]

Pokemon =17
4 Houndour- AQ
3 Houndoom- AQ
4 Growlithe- SS
3 Arcanine- SS
3 Dunsparce

Energy =16
8 Fire energy
4 Darkness Energy
4 Multi Energy

Trainers =27
4 Professor Elm's Training Method
3 Copycat
3 Juggler
3 Power Charge
3 Moo-Moo Milk
3 Switch
3 Root Fossil
3 Oran Berry
2 Town Volunteers

Strategy: Use Dunsparce to get Growlithes and Houndours into the bench, use PETM to get the evolutions, and use Root Fossil to stall for a bit when I power them up. Power Charge is to get the Multi and Darkness energies back into play.

I would use 2-2 rainbow/multi-energy just you case you power up houndoom with multi-energy, but then later you want to attach a dark energy to do more damage.

Go with Dro~'s suggestion. Also, drop the PETM's for either 4 Professor Oak's Researches or 3 Professor Oak's Research and a Fire Energy. Other than those small things, this looks like an interesting deck.
