The concept here is to leverage the Poison condtion + Sabrina's Kadabra's Life Drain attack in order to 2-shot any Pokemon.
You can either poison with the Crobat Line and then use Life Drain, or vice versa, but either way, the opponent's Pokemon will get knocked out if they can't heal or shed poison or Retreat in that 1 turn from Life Drain leaving them with 10hp and then Poison ticking that final damage.
Metal Energies to help make your Sabrina's Kadabra tankier since they're not "doing" damage - the effect of Life Drain isn't impacted, and could be used on a Zubat as well since Poison Spray isn't dealing any damage either.
Recycle Energy to help Sabrina's Kadabra move back from the active slot to swap between Pokemon for the combo.
