Q. If I take control of an equipment then move the equipment to another unit (say with Jax's ability for instance), what happens when Akshan dies?

The control of the stolen equipment is regained by the original controller, but the equipment remains attached to the unit until it dies or the gear is moved/detached by another ability.

718.5.e. Attached cards may have different Controllers from their Top-Most card.
718.5.f. Changes in Control of the Top-Most card do not impact Control of Attached cards and vice versa.
718.5.g. An Attached card still appends the abilities in its Effect Text to the Rules Text of the Top-Most card and modulates the Top-Most Card’s Might by its Might Bonus.

At the end of your turn, ready up to 2 runes.

Control of a battlefield is not lost as long as the state is closed. This changes how Arcane Shift and similar cards work, as you retain control of the battlefield as long as there are items on the chain, meaning the banished unit can be replayed on the battlefield even outside of showdowns.

187.4.c. If a player has no Units at a Battlefield and the turn is in an Open state, they lose Control of that Battlefield in the following cleanup, unless there is a Combat or Showdown ongoing there.

CR 321: while a chain item is resolving, a cleanup can not occur.

CR 323.6: while the turn is not in an Open State, there is no loss of control.

During the resolution, the state is Closed. After the resolution, the unit is pending and the state is still Closed. The condition for losing control (CR 187.4.c) is never met, and as such, you’re allowed to play the unit at the BF you were controlling if you banished the only unit at that BF. This may happen both during a Showdown and in a non-Showdown scenario.

Q. You play <Arcane Shift> on <Thousand-Tailed Watcher>. Can you use <Accelerate> to have the unit enter ready? And do you have to pay the 1 energy 1 mind power cost?

Yes, but you pay the accelerate cost.

731.+
Accelerate is functionnaly short for "As you play me, you may pay [1] and 1 Power as an additional cost. If you do, I enter ready."

Accelerate is an Optional Additional Cost to be paid as a player plays the unit with the ability.

350.+ Playng cards

• If an ability or instruction allows you to "ignore" on or more of a card's costs, set the appropriate Base Cost(s) of the card to zero.
• Apply aditional costs in any order (including Accelerate)
• Apply cost increases.
• Apply discounts in any order.

Play a 2 [M] Sand Soldier unit token for each Equipment you control. Then do this: Ready up to two of them.

When I attack, you may pay [C] to play a card with [Hidden] from your hand, ignoring its cost. If it’s a unit, play it here.

Q: What happens if I use an effect like Unlicensed Armory to prevent the death of the friendly unit I chose to kill with Baited Hook?

Baited Hook kills a unit, then uses information about “the killed unit.” If you prevent that unit’s death, there’s no killed unit, so Baited Hook can’t evaluate its Might. As a result, the check for the Might of the “killed unit” returns a null value, and you’re not able to play any unit. If the unit is killed before the ability of Baited Hook resolves, the outcome is the same.

[1][C], [E]: Kill a friendly unit. Look at the top 5 cards of your Main Deck. You may banish a unit from among them that has Might up to 1 more than the killed unit and play it, ignoring its cost. Then recycle the rest.

Q: What about cards like Blind Fury and Promising Future, which let players look at or reveal cards from the top of a deck, play one, and recycle the rest? If I can’t play that card, where does it go? It sounds like it’s too late for it to be recycled as part of “the rest.”

Hey, you’re pretty sharp! For most cards that let you play something, it’s easy to put the card back where it came from if you can’t play it. The Harrowing would put it back in your trash, Ava Achiever would put it back in your hand, and so on. But when the card came out of a deck, which is both secret and randomized, it’s not so simple.

To provide a clear and easy answer to this question, four cards in set 1 that let you play other cards from decks are receiving errata. They’ll each banish the card before instructing a player to play it. If the card can’t be played for any reason, it just stays banished. This is a small functional change, but it’s one we feel is well worth it to avoid the fuss of getting these cards back into a deck somehow.

Q. You play Bellow's Breath repeated, targeting Stellacorn Herder and 2 Traveling Merchants at Void Gate. Your Opponent plays Flash in response, returning the 2 Traveling Merchants to base. What happens next (other than your opponent discarding 1, drawing 1 twice)?

You choose either the Herder or the two Merchants to die.

352.11.b
If the group of targets no longer collectively fulfill the targeting restriction as the spell or ability resolves, that spell or ability's controller can choose a subset of the original targets that fulfills the targeting requirement for the spell or ability to affect.

Q. Can I sacrifice the unit I want to equip Blade of the Ruined King to?

No.

355.16 A player may not make choices during this step that will deterministycally result in illegal choices or actions later in this process unless they have no choice.
_Example: A player plays a card which reads "as an additional cost to play this, kill the unit you control with the most Might. Give a friendly unit +[M] equal to the killed unit's Might this turn. predict 2." They cannot choose to target their unit with the highest Might during this step of finalization.

[Action] (Play on your turn or in showdowns.)

Each opponent reveals the top card of their Main Deck. Choose one and banish it, then play it, ignoring its cost. Then recycle the rest.

Card text now reads as:

[Action] (Play on your turn or in showdowns.)

[Repeat] [1] (You may pay the additional cost to repeat this spell's effect.)

Give a unit [Assault 2] this turn. (+2 [M] while it's an attacker.)

Card text now reads as:

[Hidden] (Hide now for [A] to react with later for [0].)

Choose a battlefield. An opponent reveals their hand. You may choose a unit from it. They play that unit to that battlefield, ignoring any and all costs. If they do, then do this: [Stun] it. (It doesn't deal combat damage this turn.)

Q. Can Tasks interrupt finalization?

Corner case, but useful to understand the deep process.

I target a 1M unit that has 1 buff and 1 damage marked, paying the cost by spending its buff.

Would this result in the unit dying before the spell finishes finalizing (cleanup fires between step 4 and step 5, unit is dead by Check Legality)?
Or does "pause" not apply mid-finalization?

RIOT ANSWER (15/04/2026)

Tasks cannot interrupt finalization.

This card is now banned.

Q: So as I play Charm, I have to say not only what unit I’m moving it, but where I’m moving it to?

Yes. This is a change from prior rulings. This means that move effects that don’t mention a destination (like Charm) work the same way as those that do (like Showstopper).

You may pay [C] as an additional cost to play me.

When you play me, if you paid the additional cost, draw 1.

[Reaction] (Play any time, even before spells and abilities resolve.)

Choose a friendly unit. This turn, increase its Might to the Might of another friendly unit.
