Persistence

Flash, Flying
If you would lose the game, instead set your life
total to its starting value, shuffle your graveyard
into your library, set your poison counters to zero,
and create an emblem with "You have no max
hand size. At the beginning of your draw step, if
you have less than 10 cards in hand, draw until
you have 10 cards in hand. Spells you cast have
Split second." Exile Persistence. It cannot be sent
to your command zone.
