In "", a player may declare a mulligan after drawing their initial hand at the beginning of each game. If a player chooses to do so, that player shuffles their current hand back into their deck, draws a new hand of seven cards, then puts one card on the bottom of their library for each time they've mulliganed this game. The player may repeat this until satisfied, or until the number of cards in their hand reaches zero. The mulligan process has changed drastically over the history of the game. The current style is known as the "London mulligan", as it was first used at a Mythic Championship tournament held in London.
