Ok Gastly. If you can't see Abra, I don't know how he expects to taunt you. Use Psychic to redirect the Shadow ball into hitting the clone of Abra. That should be enough to destroy it. Now why do you Taunt Abra, so he can't use Safeguard, and finish off with a nice long wet Lick over Abra's face.

Slowpoke, start off with Psychic to crush Staryu's Substitute. then use Bide to absorb both those electric attacks and send it all right back at Staryu.
