Yaroli, Spirit Speaker

Whenever you cast a noncreature spell, create a
1/1 spirit creature token.
Whenever a nontoken creature enters the battlefield under your control, you may exile
that creature and each spirit token you control.
If you do, for each spirit sacrificed this way,
create a token that is a copy of the nontoken
creature with haste and "Exile this creature at
the beginning of the next end step."
