Question 8 Player 1 controls a battlefield with a Mountain Drake at that battlefield. Player 2 moves their Travelling Merchant and Yasuo, Remorseful to that battlefield. A combat begins, and Yasuo, Remorseful's attack trigger targets the Mountain Drake. It Resolves. Player 1 plays Facebreaker, which stuns the Mountain Drake and the Yasuo. Player 2's hand is empty. How does the combat resolve? ANo Units are Killed, All Units Recall, Player 2 draws 1 BTravelling Merchant is Killed, Mountain Drake Recalls CNo Units are Killed, Yasuo and Travelling Merchant Recall, Player 2 Draws 1 DMountain Drake is Killed, Player 2 Conquers ENo Units Are Killed, Yasuo and Travelling Merchant Recall

The correct answer is C: No Units are Killed, Yasuo and Travelling Merchant Recall, Player 2 Draws 1. The resolution follows this sequence:

1. Pre-Combat Movement and Triggers

• Move Trigger: When Player 2 moves Traveling Merchant to the battlefield, its "When I move" ability triggers.
• Resolution: Per RiftJudge FAQ #11356, Player 2 (who has an empty hand) skips the discard and draws one card. This resolves on the chain before the showdown begins (FAQ #4077, FAQ #3379).

2. Combat Setup

• After the move trigger resolves, the showdown begins. Yasuo, Remorseful is the attacker and Mountain Drake is the defender.
• Yasuo's "When I attack" trigger goes on the chain. Per FAQ #6717, players can react at this time.

3. Facebreaker Interaction

• Player 1 plays Facebreaker. The spell resolves, stunning both Yasuo, Remorseful and Mountain Drake.
• Stunned units do not deal combat damage this turn.

4. Combat Resolution

• Damage Step: Because both the Mountain Drake and Yasuo are stunned, they do not deal combat damage. No units are killed by combat damage.
• Combat Cleanup:
  • Heal all units: All units are healed.
  • Recall: In a standard combat, after damage, attackers are recalled if defenders are still present (Rule 466.1.a.2). Because the Mountain Drake remains on the battlefield, the attacking Yasuo (and by extension the Traveling Merchant who is at the battlefield with him) is recalled to Player 2's base.

Note: I could not fully verify the specific 'stun' mechanic of Facebreaker against the provided rules, as the card text and stun definition were not included in the retrieved context.
