Narra, The Spirit Mystic

on your end step, draw cards equal to the number
of tokens created this turn.
When you cast a blue or Green creature spell,
you may pay {2}.
If you do, make a copy of that creature enter the battlefield except it's a spirit illusion token
that has haste and "When this card becomes
the target of a spell your opponent controls, sacrifice it."
-Exile it on the next end step.
