With Dark Prophecy or Premonition or Scrying Mirror, this card is decently reliable even for non-token manipulation mystics.
The real problem is that there's a lack of really good recur targets. Your spells with charges don't self-discard. Seal of the Elder Sign, Seal of the Seventh Sign, The Eye of Truth all can't be recurred. Deny Existence (5) can be, but it's a defensive card, not a combo piece. If there were a really strong repeated mystic event, Dayana Esperence would be much stronger than she already is. The best target is probably just a Ward of Protection or a Recharge (4).
Also worth mentioning that Eldritch Inspiration (1) allows you to recur two cards.
