Dragon - Champions and allies designated as dragons gain bonuses or penalties based on other card's special powers. Many dragons are monster champions, though they can be of any type. Not all dragons are flyers even if the picture seems to indicate otherwise.
AR - Augmented Reality card. Scan QR code to inspect the card. AR cards distracts players in real life. If AR card participated in the battle, opponents draw one fewer card than normal on their turns (minimum of one card) until the next battle.
Flyer - Champions or allies with the ability to fly can attack any realm, regardless of its position, by flying over intervening realms. If a card does not specify that it's a flyer, it is not, even if the picture shows wings or the name of the card implies the ability to fly. Flyers cannot attack realms that specifically state that they are immune to flyers or that flyers cannot attack. The ability to fly is not automatically granted to allies unless it specifically states so on the flyer's card.
