Checkmate deck for expanded
The goal is to use Naganadel's GX attack to give both players 3 prize cards
On your next turn, use Peonia to place Jirachi Prism Star into your Prize Cards
Then, if necessary, use Electrode or Electrode-GX to force your opponent to have one prize card
Then use Slowbro's Twilight Inspiration to take two Prize Cards, one of which is Jirachi Prism Star, and then bench it to take your final prize
Arceus helps you get missing pieces of the combo with Starbirth
