Utopia, the Light of Hope

You may pay {w}{w}{w} and tap two untapped
creatures you control with converted mana cost
4 or less rather than pay this spell's mana cost.
If one or more creatures would deal combat
damage to you or a permanent you control,
you can pay {1} for each of those creatures,
prevent that damage.
Once each turn, you can sacrifice a non-Land
permanent: draw a card.
