Queen of Sheba

At the beginning of combat on your turn, create
X tokens that are copies of another target
creature you control, where X is one plus the
number of instant and sorcery spells you've
cast this turn. They gain haste. Exile them at the beginning of the next end step.
"I am an illusion. I disappear like a mirage in a sea
of sand. Even so, I hope that stories of me will be
passed down along with your great deeds."
—Queen of Sheba
