This deck is a really powerful meme deck. It wins the game in two turns quite often.
The goal is to use Electrode-GX to ramp energy onto Liepard and use Assist with Reveral and Counter energy to get Supreme Puff-GX to work. Then use Will and assist with Tapu Lele-GX's Energy Drive to KO and win the game. Very simple.
Try to draw your entire deck as quickly as possible to get your cards and hand ready for the big turn. Tapu Lele-GX and Togepi & Cleffa & Igglubuff-GX are the cards you most want to use, but try to wait until the game-winning turn to play them.
If you have any suggestions to streamline the trainer or Pokémon count, or any questions whatsoever, please leave a comment! Have fun with this fun deck featuring the cutest tag team mon!
