Collectors prize SPs for their stunning art: each set from OP-03 onward has its own SP art theme (wanted posters, character portraits, stained-glass mosaics, etc.)
If you have Muk or Wheezing in your Active Spot in a match, you can play the Koga Trainer card
Die rolls that can't have a numerical result, such as the planar die roll, don't count
If they wanted a second Kiki-Jiki like effect (aside from Splinter Twin), Fable of the Mirror Breaker is a decent option
And to make sure you know when the boxes are available, set up restock alerts through StockX, Honey, or even Twitter/X accounts that track Pokmon product drops
For starters, Green Goblin, the deck its value is currently tied to, is on a great trajectory at the moment
