This is lordjoechu giving you a strategy that I have not yet seen posted before. It is Dark charizard plus darkness energy. Dark charizard first a attack(nail flick) is 1 for 10. With Darkness energy it becomes 1 for 20. The second attack(continuous fireball) requires RR and dose 50 times number of heads you flip for each fire energy attached it. Then you discard a fire energy for each time that you flip a heads. But with Darkness energy attached to Dark Charizard as well as 2 fire energy you could proportionally( considering you flip 1 heads a turn) do 60 damage that is grate for just 3 energy. Finally because he has dark in his name he dose not take any damage.
