Infinity

When Infinity enters you get an emblem with
"you have no maximum hand size."

If a player loses the game or a player wins the game instead shuffle each player's hand, exile, graveyard and battlefield except Infinity, into their library . Then have each player gain or lose life until they have 40 life, have each player draw 7 cards, and put an Infinite counter on Infinity.

{1}, Sacrifice Infinity: draw X cards gain twice X life where
X is the number of Infinite counters on Infinity
