Why do I attack first again?

Beh. Good job ye both....
Wrath, Fire Blast at anything that comes near you. If nothing comes near you, Flamethrower the Steelix. Keep that up for the whole round.

Taunt, grab Scyther and repeatedly smash him into the Steelix with a Psychic grip. Thunderbolt him for the rest of the round.
Obviously use Magic Coat to repel stat effects. Jump in front of Wrath and repel them from him if need be.
