There are exactly 150 cards in Orbs CCG, with 25 cards per color, which are split into three different rarities-- common, uncommon, and rare. The rarity of a card can be found by looking at the top of the card: if the background to the name is gold, it's rare; if the background is silver, it's uncommon; if the background is bronze, it's common. In the store, the rarer the card the more it will cost. Likewise, when selling cards, the rare cards return more Orbucks than uncommon and common.
