Caretaker of the Divine

When Caretaker of the Divine enters the battlefield, if you already have cast a non-creature spell this turn, create four 0/1 green Rabbit creature tokens with haste. They get
+1/+0 until end of turn. Copy this effect for
each spell you've cast so far this turn.
{1}{u}{u}{r}{r}: Return Caretaker of the Divine to
the battlefield under your control, then sacrifice it.
