Deck plays hyper aggressive and covers most of its counter (imo, please comment and lmk if there's any suggestions you guys have).
Lucarios's ability combined with Tyranitar's Lightning Rampage, as well as super quick energy cycling and placement with Garchomp makes this a relatively straightforward deck to play.
Jirachi to cover Sableye etc. and Greninja for drawing cards. Lumineon+ Forest Seal Stone can help in pinch situations when you need either that rare candy or Tyranitar/Garchomp.
Edit: The deck tends to struggle with Mimikyu, so I swapped out Klaras for Cancelling Colognes.
