Spindling Moirai

Ward {3}
If the Moirai would leave the battlefield, shuffle
them into its owner's library.
Whenever you gain life, choose one at random -
• create that many 1/1 white sheep tokens.
• Sry X, where X is twice the number of life you
gained.
• put up to one nonland permanent into its
owner's library third from the top. If you do,
discard a card at random.
