Sensei Yu Discipling Mulligan.

[santaclaws01]

If Sensei Yu uses his (0) action Disciple to use Jakob Lynch's (0) action Mulligan and discards aces, do you get the aces back?

Disciple reads: This model immediately takes a (0) action belonging to a friendly Leader in play. Any cards this model would discard during the course of the action are shuffled into its desk instead after completing the action.

Ace in the Hole reads: When an Ace from this Crew's deck would be placed in the discard pile during another friendly model's Activation, this model may place it in its hand instead after the Action resolves.

My reading of it leads to yes because they both have the same timing, which would mean I get to chose in what order they would happen, but I wanted to make sure before potentially getting 3 cards for free against an opponent

The aces would be shuffled into the deck - the Ace in the Hole ability only happens after the Disciple ability is resolved, by which time the aces have already been shuffled into the deck.

That part of Disciple was basically written specifically because of this interaction with Mulligan - otherwise it would just be an absurd ability!

The cards that Yu would discard (including the aces) are not discarded, they're shuffled into the deck after completing the Mulligan. No cards "would be placed in the Discard pile", so Ace in the Hole never comes into effect. There are no timing conflicts.

As Shadowfane mentions, the given wording of Disciple was written specifically to break this exact interaction.

Well they would be discarded, because the first thing you do with Mulligan is discard cards, but I'm just being pedantic.

That's not being pedantic, that's ignoring the fact that the game rules define how things work. 

The game defines "discard a card" as:

Cards that have been flipped, cheated, or discarded are moved to the top of that player’s Discard Pile face up. Players may not look through Discard Piles unless allowed to by a special rule. The top card of each player’s Discard Pile should be visible to all players at all times. When a player moves multiple cards to the Discard Pile at once, she does so in whatever order she chooses, but must show all players what cards are being moved.

As an example of context:

Once all cards are flipped, the model chooses one to use as its active card. A model flipping cards with one or more + chooses one of the flipped cards as the active card and discards the others to the Discard Pile.

So in the course of a flip with , you flip two cards, choose one to keep, and then follow the instructions for "discard a card" for the other one.  But, Disciple changes the instructions for "discard a card".

Disciple says:

Any cards this model would discard during the course of the action are shuffled into its desk instead after completing the action.

So Disciple changes the definition of discarding a card to "Place the cards aside, and shuffle them directly into the deck" rather than placing them face up in the discard pile.

Ace in the Hole specifies

When an Ace from this Crew's deck would be placed in the discard pile during another friendly model's Activation, this model may place it in its hand instead after the Action resolves.

 While Disciple applies, the condition "would be placed in the discard pile" doesn't apply to discarded cards simply because you're not placing discarded cards on the discard pile.

So that means Mulligan is completed and then Disciple resolves, correct?

Ah, so thats how that goes. I was thinking the cards are discarded, and then at the end of Mullgian, but before the end of disciple, the cards that were discarded are instead shuffled into the deck. I wasn't arguing that you could keep the Aces after the first person answered, because I can definitely see why it would be worded so as to avoid that interaction.
