This Japanese set is nowadays mostly known as 1st Starter Pack
~26 Pokemon only, no backing Appears to be a very basic proof-of-concept CSG1401030938-026_OBV19203134 717 KB Alpha Playtest Basic artwork: Red/Green Sugimori stock images for Pokemon, trainers have Ooyama/Kinebuchi artwork
Airtight or semi-sealed edges Helps keep out dust and moisture, especially in humid environments or near windows
My examples here are a playtest card that is not for Constructed play, a Commander format-specific card, and a superpowerful card translated from Arena's Alchemy to paper
Also, see the following video by Cimoooooooo for another great overview
When you have Virtue of Persistence on the field, youll be in a very good place each turn, though this card will likely be a lightning rod for removal
