MAGIC: THE GATHERING
Each player shuffles his or her hand and graveyard into his or her library, then draws seven cards. (Then put Timetwister into its owner's graveyard.)
Timetwister is one of the original "power nine", a group of potent and collectable spells that debuted in Alpha. While Timetwister allows both players to draw 7 new cards, the opponent rarely lives long enough to play theirs after Timetwister spell resolves.
