Each Crate consists of 5 cards. Cards are divided into Common, Uncommon, Rare and Mythic. There is also a gold foil version of the cards, the use of gold foils is yet to be announced by the team. We have total of 5 types of crates
Great Overview but actually the faction crates only has 3 cards inside, other than that other crates has 5.
