It is a card that can be equipped to quite a few cards, and it is a stat increase card corresponding to the Asu type!
It is said that it is a card used a lot in video games, and like the stat boost cards introduced before, it doesn't seem like a card that had a big impact.
Making cards like these for each race and filling the slots in the pack.. It must have been really sad when I opened the cards and only these cards came out lol
