I notice that even for rare cards, there are some disparity so I'm going to list out what I think is the rarity for the rare cards. I'll be using Yugioh naming to represent them. Please note that this is from my purchase experience of 177 Templar packs and may not represent the exact rarity ratio, it may just represent my luck!
Legend
Ultra Rare - Out of 177 packs, less than 5 copies, the rarest rare-s
Super Rare - Out of 177 packs, very close to or about 5 copies, the uncommon rare-s
Normal Rare - Out of 177 packs, easily more than 5 copies, the common rare-s
Cards will be listed with the card type in brackets. I'll leave the card details to another post or hopefully Ubisoft releases the card list guide soon.

An Auction House feature will be added to the game soon and players will be able to sell their cards. I think the Ultra Rare cards are going to fetch a higher price and may even reach Assassin Rare prices.
