The Test Set Exterminator Set introduced the types of cards which would be the baseline for the cards released over the next three years. As shown in this "Issue 1" accompanying leaflet, there were "Character Cards" and "Bonus Cards" shown featuring the then new National Release designs. Looking closely you can see that the cards themselves have a rarity symbol, and the bonus cards feature revamped circle warning circle rather than the yellow warning triangle seen on the Test Set cards.
This leaflet also showed the rarities of the cards, detailing the "Common", "Rare", "Super Rare" and "Ultra Rare" cards. What was great to see within these magazines is the artwork unhindered by either foil or the lenticular plastic. Sadly, these artworks are lost or gatekept and therefore will only be visible through the magazines.
The second page of the leaflet goes into further detail regarding the cards themselves. As seen there are details regarding the Card Numbers, Power Icons, Card Description, Set Name, Set Number, Deck Icons, Double Ratings and Skill categories.
