As Foretold (Anime Borderless) (Confetti Foil) [Wilds of Eldraine: Enchanting Tales]

At the beginning of your upkeep, put a time counter on As Foretold.

Once each turn, you may pay 0 rather than pay the mana cost for a spell you cast with converted mana cost X or less, where X is the number of time counters on As Foretold.
