You will need to alternate between Psydrive and Psychic Sphere while adding more Energy to the mon, and I dont recommend putting them into your Active Spot until they have at least five Energy on them, so you can at least use Psybeam twice in a row and hopefully sweep through your opponents Pokemon and get ahead of them in terms of Prize Points
