This is the Flarecanion deck I made I have space for two still which would fit the 2-2 Octillery line If you have 1 Shaymin then you can get another Flareon or another trainer. The way this deck works is that you want baby Volcanion as your active early game. You want to try to get 2 Volcanion EX's on the bench and 1-2 Flareons. Baby Volcanion will never have more than 1 energy on him because his purpose in life is to set up Flareon. I used Scorched earth just in case I didn't have Volcanion EX set up yet to discard my fire energy, and it gives me some draw power if I don't have Shaymin. If things go well first attack should be 80dmg from baby Volcanion. Flareon and someone else gets energy. Second attack turn Flareon should be able to attack by using his ability and attaching an energy. I generally don't yet I let baby Volcanion do more work and sometimes pull off another 80dmg attack. Third attack turn is usually when I pull Flareon up.
