from the little text we have on this uncommon, it's likely going to be very similar to plot, you pay a cost to exile the card, then you can cast it for free at a later time, I'm guessing at the start of the next turn because it says "beginning" and casting a card for less mana at the end step doesn't make much sense

the timing restriction of the start of your turn might make up for the fact you're likely paying less mana for something
