How do you know if a Pokemon card is ultra rare?

Look at the bottom right corner of the card. If there is a circle, the card is common. If there is a diamond, the card is uncommon. If there is a star, the card is rare. If there is a star inside a circle, the card is very rare. And if there are 4 squares arranged in a diamond, the card is super rare. Look at the bottom right corner of the card.
