You will have to guess 25 Clash Royale cards(October 2017) in 5 minutes. You will be given 3 hints for each one: It's rarity, elixir cost and a clue on its looks, actions or trivia. The last 10 will have harder hints and the last 5 are challenges and only have one hint. Good Luck! :)
P.S. Please give me feedback and compliments in the comment section!!
