Fastbond = Life gain

You may play any number of lands on each of your turns. Whenever you play a land, if it wasn't the first land you played this turn, this enchantment deals 1 damage to you.

You may play lands from your graveyard.

Flying If noncombat damage would be dealt to you, prevent that damage. You gain life equal to the damage prevented this way. When Purity is put into a graveyard from anywhere, shuffle it into its owner's library.
