It's more or less a Resourceful but for spells. Being , it has a game attached to it. I think this is mostly a chaos bag Mystic kind of card, most likely limited to Jacqueline, but fun if you like gambling. Most Mystics will prefer to take Fearless, Guts (2), or maybe Defiance for a willpower boost.
Max 1 committed per skill test.
After you commit Prescient to a skill test, name "even," "odd," or "symbol." After this test ends, if a chaos token of the named type was revealed during this test, you may return a Spell card from your discard pile to your hand.
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 choices probably are Grotesque Statue and Ward of Protection.
That said, this card is more flexible than Dayana since you don't have to predict which spell you'll need to repeat. Enemies congregating? Storm of Lightning. Frozen in Fear? Alter Fate clears. About to die? Deny Existence (5).
Also worth mentioning that Eldritch Inspiration (1) allows you to recur two cards.
