Only dark energy.
Darkrai EX is the only attacker.
Shaymin and Aerodactyl in the bench for their passives. Shaymin heals 10 points per turn to each pokemon and Aerodactyl prevents evolving active pokemon.
Cyrus can delay a heavy hit by forcing the opponent to waste an energy getting them back into play, or allow you to pick off a weakened for that has retreated.
