Jeska’s Will helps red Commander decks turn one spell into a burst of mana, temporary access to more cards, or both. Controlling a commander as you cast it lets you choose both modes, making it particularly useful for a turn when you want to develop several pieces or finish a game.
The mana mode adds red mana based on the number of cards in a targeted opponent’s hand when the spell resolves. The other mode exiles your library’s top three cards and lets you play them that turn. You still pay their costs and follow normal timing rules. An exiled land also needs an available land play, so consider casting Will before using your land drop.
Prosper, Tome-Bound provides a direct payoff for the exiled cards: each one you actually play from exile creates a Treasure. Birgi, God of Storytelling adds red mana as you cast follow-up spells and lets that mana remain available through steps and phases for the turn. These partners help turn temporary access into a longer sequence of plays.
Look at your available colors before committing. A large amount of red mana does not automatically cast every multicolor card you might exile, and unused cards remain exiled after the turn. Opponents can also reduce the targeted player’s hand before the spell resolves, lowering the mana produced. Jeska’s Will rewards planning around the whole turn rather than treating its modes as guaranteed profit. It is at its best when your commander is active and your deck has productive ways to spend red mana immediately.
Unofficial proxy card for casual play and testing where your group permits it.
