This game is smart, fun, funny and free! Yes, you got it. No ad pop-ups, no energy to buy so you can play. It's nice having a game that's CHOOSE to buy, not pay to win. Three days and I've already collected over 500 cards. The trading system is and super cool. And you'll have no trouble meeting friends. Many. If you like TCGs such as MTG or Gwent, this game will more than met your expectations. Cons: It crashes once in awhile, and the buttons aren't as responsive as they could be...
