This is designed to be played as a "comeback" version of the deck.
The main strategy is out the gate to set 1 garchomp up and start poking to build energy onto your Decidueye.
Decidueye and Samurott are your main draw engines.
Samurott is also a good single prize damage dealer to put pressure on. Late game your opponents bench will be full of damaged mons - you then use the double turbo energies to knock them out with garchomp.
Good matchups
Charizard
Future Box
Lugia Vstar
Snorlax Stall
50/50
Lost tina (you can replace a double turbo energy with mist energy to protect from their main attack)
Ancient Box
Miraidon (use decidueye for this match up)
Dialga Vstar
Bad match-ups
Hands Turbo - if you go first you have a chance - however if they get a double energy attach using generator turn one, its GG - Try to avoid using Garchomp at all costs.
Unfortunately deck is just degenerate and its an uphill battle to win - even with decidueye Vstar
