Jace, Architect of Thought
Duel Decks: Jace vs. Vraska — mythic
Legendary Planeswalker — Jace
Jace, Architect of Thought rulings:
2012-10-01: Jace's first ability creates a delayed triggered ability that triggers whenever a creature an opponent controls attacks. It doesn't matter which player or planeswalker that creature is attacking.
2012-10-01: You pick one of your opponents when Jace's second ability resolves. The ability doesn't target that opponent. All players may see the revealed cards and offer opinions. You (not your opponent) choose which pile is put into your hand and which pile is put on the bottom of your library.
2012-10-01: Piles can be empty. If one of the piles is empty, you choose to put all the revealed cards in your hand or on the bottom of your library.
2012-10-01: When resolving Jace's third ability, you search each player's library (including yours) and exile the nonland cards before casting any of them.
2012-10-01: For each library, the search is complete only when you explicitly say it is. For example, you can look through one player's library, set that library down, look at another player's library, choose a nonland card in the first library, then choose a nonland card in the second library. Don't reveal any cards from those libraries to any other player until you exile them.
2012-10-01: You cast the cards by putting them on the stack one at a time, choosing modes, targets, and so on. The last card you cast will be the first one to resolve.
2012-10-01: When casting a card this way, ignore timing restrictions based on the card's type. Other timing restrictions, such as “Cast [this card] only during combat,” must be followed.
2012-10-01: If you can't cast a card, perhaps because there are no legal targets available, or if you choose not to cast one, it will remain exiled. Jace's ability won't allow you to cast it later.
2012-10-01: If you cast a card “without paying its mana cost,” you can't pay alternative costs such as overload costs. You can pay additional costs such as kicker costs. If the card has mandatory additional costs, you must pay those.
2012-10-01: If a card has in its mana cost, you must choose 0 as its value.
