Keeper of the Quiet Hour rulings

2026-08-21
Some spells and abilities that empower Jace may require targets. If each target chosen is an illegal target as that spell or ability tries to resolve, it won't resolve. You won't empower Jace.
2026-08-21
Empower Jace won't let you put loyalty counters on nontoken Jace planeswalkers. However, if you control a Jace planeswalker token that you got another way (such as an effect that creates a token that's a copy of a permanent), empower Jace will put loyalty counters on that.
2026-08-21
To empower Jace N, if you don't control a Jace planeswalker token, create a blue Jace planeswalker token with 0 loyalty, "[−1]: Surveil 1," and "[−3]: Draw a card." Choose a Jace planeswalker token you control. Put N loyalty counters on it.
2026-08-21
If you control a Jace planeswalker token, you can't choose to create a new one when you empower Jace. You have to put the loyalty counters on your existing Jace planeswalker token. In the rare case that you control multiple Jace planeswalker tokens, you'll choose one of those tokens to put the loyalty counters on.

Keeper of the Quiet Hour keyword rules

Surveil Rule 701.42

To “surveil N” means to look at the top N cards of your library, then put any number of them into your graveyard and the rest on top of your library in any order.

If an effect allows you to look at additional cards while you surveil, those cards are included among the cards you may put into your graveyard and on top of your library in any order.

If a player is instructed to surveil 0, no surveil event occurs. Abilities that trigger whenever a player surveils won’t trigger.

An ability that triggers whenever a player surveils triggers after the process described in rule is complete, even if some or all of those actions were impossible.
