as mentioned before, your turn ends, so you can't use the power again.
the way to use it, IMO, is to make a T2 90 damage by comboing with himself... after that, you could try to put down some Holon Circles so that you can attach NRGs while avoiding hits from your opponent. Tech in 1 Latios ex d for free retreat and prevent ex damage, and 1 Latios HP with Dual aura to stop evolved bodies. It may also be possible to combo with Swampert ex (whose power also ends your turn, but loads you with 3 NRGs) to quickly get ready for the next big hit.
