Narra, The Spirit Mystic

When Narra, The Spirit Mystic enters the battlefield, Draw a card for each basic land
you control.
When you cast a blue creature spell, you may pay {2}. If you do, make a copy of that creature enter
the battlefield except it's a spirit illusion with
haste and "When this card becomes the target of
a spell your opponent controls, sacrifice it."
Exile it on the next end step.
