Ah, tricky, though not Tricky enough! Without your Prankster, you aren't nearly as fast as me, so Gastro Acid away that obnoxious ability, THEN Thunder Wave him into a tight position, and finally pin him down with an Electroweb!
If he managed to Taunt before the Thunder Wave hits him, replace the Thunder Wave with Energy Ball!
Gastro Acid - Thunder Wave - Electroweb
Energy Ball over Thunder Wave if Taunted before the Thunder Wave takes place.
