Stem The Tide

All instances of X on this card have a value equal
to the number of players in the game.
Each player creates X 1/1 white Soldier creature
tokens and X 1/1 blue Wizard creature tokens.
At the beginning of each upkeep, each player
must sacrifice a creature. If a player is unable to sacrifice a creature, that player loses the game.
