Kaijudo Rarity Overview

Cards in the Kaijudo TCG are grouped into five different rarities: common, uncommon, rare, very rare, and super rare – and you will find familiar creatures from Kaijudo: Rise of the Duel Masters at each rarity.
Common cards show up with the highest frequency in booster packs, and include staple cards which form the backbone of many decks!
Uncommon cards play well with commons, adding another lens to look at your other commons through.
Rare cards have more unique, intricate effects than common and uncommon cards, providing many cards that are great to build around!
The higher rarity Kaijudo cards are premium foils and look different from lower rarity cards:
Very Rare cards feature colossal creatures and dynamic spells which have an exciting impact on the game!
Super Rare cards are the rarest and most awe-inspiring cards in Kaijudo. They have an incredible foil treatment art that bursts out of the card frame!
