From The Bakugan Wiki
In the Bakugan Battle Planet toyline/trading card game all Ability Cards have a Card rarity such as Common or Rare. The rarer the card, the harder it is to pull from a Card booster pack. Character Cards do not have rarities.
Currently there are five types of rarities:
- Common (CO)
- Rare (RA)
- Super Rare (SR)
- Awesome Rare (AR)
- Bakugan Elite (BE)
Additionally, cards have the chance to be FOIL/HEX (holographic), therefore, HEX Common is rarer than Common Cards. The true rarest card one could pull is a HEX Bakugan Elite Card.
Bakugan Elite is the highest rarity of Ability Cards in the Bakugan Battle Planet toy-line. Technically, HEX/Holographic versions of Bakugan Elite are the true rarest cards one can collect.
