Hearthstone

The match begins with a coin toss to determine who goes first, followed by both players drawing their starting hands: three cards for the coin toss winner, four for the other player. And because going first does offer a slight strategic advantage, the loser of the coin toss also gets The Coin: a special zero cost card that temporarily increases your mana by one! You can mulligan as many cards from your starting hands as you like. Once both players accept their hand, the match proper begins.
