rather than expending Ink to play the card, youre sacrificing a card
An eleventh energy type, Fairy, was recently phased out of the game as part of the Sword & Shield expansion
It was a neat thing back then, yes, but hadnt that already been done once
Take a look: When you split up the Dot Code part of the card into what they would look like under Red, Green and Blue light well, you clearly get some different examples of what they look like: The blue view lol, nope The green view a little better, but some of the stray printing it might interfere with the e-Readers ability to read the Dot Code bar properly The red view now THAT is a nice clean pattern
Though quite often, players may keep track of these with whatever they have to hand, youll find Token cards in Booster Packs and just like any other card, they can be purchased as singles via eBay or other sites such as Total Cards
A noteworthy example is Bulbasaur compared to Charmander and Squirtle
