| "question": "My opponent controls Vex Apathetic. I play Tideturner during my opponent's turn. Can Tideturner move before Vex's stun resolves?", |
| "canonical_answer": "Yes. When multiple players control triggered abilities that trigger simultaneously, starting with the Turn Player and proceeding in Turn Order, each player orders their triggered abilities on the chain. On the Vex controller's turn, Vex's trigger goes on the chain first and therefore resolves after Tideturner's ability, allowing Tideturner to move before getting stunned.", |

| "id": "eval-014", |
| "question": "My opponent controls Vex Apathetic. I play Tideturner on my own turn. Can Tideturner move before Vex's stun resolves?", |
| "canonical_answer": "No. Playing Tideturner on your own turn results in Vex resolving first, which prevents Tideturner from moving before it is stunned. The turn player orders triggers first, so Vex's trigger resolves before Tideturner's ability.", |

| "canonical_answer": "No. Evelynn's ability states 'when you play me from facedown on your turn.' Since it is the attacker's turn, not Evelynn's controller's turn, Evelynn's triggered ability does not fire. Evelynn simply adds her might to the battlefield without moving the attacker's unit.

| "question": "My opponent defends with Fiora Peerless. I move a unit into the battlefield, then immediately try to play Rengar Trophy Hunter as a reaction to add another attacker. Does Fiora's triggered ability still resolve and grant double might?", |
| "canonical_answer": "Yes. Fiora Peerless has a 'when I attack or defend' trigger that goes on the chain as soon as she is assigned defender designation. This happens before there is a chance to play Rengar Trophy Hunter as a reaction. Once the ability is on the chain, it resolves even if Rengar is played afterward. The same applies to Kha'Zix.", |

| "question": "Does the Challenge spell create a showdown? Does the unit dealt damage by Challenge get healed afterward?", |

| "question": "When a unit is sacrificed as an additional cost to play a card, does the unit die before or after the card is placed on the chain? Can the opponent react to the sacrifice?", |
| "canonical_answer": "The unit must be killed before the card is placed on the chain. When the reaction window opens, the unit is already dead. Paying the additional cost is not a reflexive trigger, so opponents cannot react to the sacrifice itself.", |

| "question": "If both Angel Guardian and the unit it is attached to are given the Temporary keyword, what happens when Temporary triggers?", |
| "canonical_answer": "Both units have separate Temporary triggers that fire during the beginning phase. You can choose the order of those triggers, allowing the unit's Temporary to resolve first, which kills the Angel Guardian. However, the unit still has Temporary and will attempt to kill itself again at the beginning of the following turn.", |

| "question": "Can Brambleback, when he has conquered a battlefield and is mighty with an equipment, tap 2 runes to draw 2 cards at Sunken Temple?", |
| "canonical_answer": "Yes. While a battlefield is controlled, its controller controls its abilities (CR 187.6.a). Brambleback doubles your conquer effects. Sunken Temple is your conquer effect because you now control the battlefield, so it triggers twice provided you pay the appropriate cost and Brambleback was mighty when conquering.", |

| "question": "If my opponent has Fiora Peerless on the battlefield and I attack with a unit, then react with an Ambush unit during the showdown, does Fiora's trigger still resolve?", |
| "canonical_answer": "Yes. If you react with an Ambush unit during the showdown, you are doing so in reaction to Fiora's trigger, which will already be on the chain and will resolve. To prevent Fiora's trigger, you would need to Ambush in response to a movement trigger that opens before the combat begins, if your unit had one.", |

| "question": "If I attack a battlefield controlled by Fiora Peerless with Master Yi Legend, what is Fiora's final might?", |
| "canonical_answer": "Fiora's final might is 10. Master Yi Legend's passive is a continuous effect: the moment Fiora defends alone she gets +2 might instantly, making her 5 might, which is then doubled to 10 by her own ability. If at any point during combat a reaction unit is played alongside her, she would lose the +2 from Yi's passive.", |

| "question": "If I move an Irresistible Faefolk and a Vi into an empty battlefield and pull an enemy unit in, does Vi get her attack trigger to stun?", |
| "canonical_answer": "Yes. Vi still gets the attack trigger. Units moving to a battlefield apply Contested status if that battlefield is not already contested and the unit's controller does not already control it (CR 187.3.a.1). All units get their Attack or Defend triggers the first time they gain Attacker or Defender designations each combat. Note that if Vi is removed in response to her trigger, the stun will not resolve.", |

| "question": "Can I activate Irelia Legend's Blade Dancer ability to ready a unit even if she is already readied, and still get value?", |
| "canonical_answer": "Yes, in one specific scenario. After winning combat with Irelia, you can activate Blade Dancer's conquer effect even if she is already ready, placing the ability on the chain. You can then chain Blade Dancer's conquer effect with another card such as En Garde, then activate Blade Dancer's exhaust ability to ready a unit and pay the recycle cost. Because everything is on the chain, the order resolves as: Blade Dancer conquer effect, then En Garde, then Blade Dancer exhaust-to-ready effect. This allows you to ready your unit and your Legend even though she was already ready when combat was won.", |

| "question": "If I play Marching Orders with Repeat, do both damage instances happen simultaneously or sequentially? Can I kill two enemy units of equal power to my unit?", |
| "canonical_answer": "The damage instances happen sequentially, but units only die from damage during the next cleanup after the spell fully resolves. This means both instances of damage are applied before any unit dies, so you can effectively remove two enemy units of equal power to your unit with a single Repeated Marching Orders.", |

| "question": "I have a Reflection Token of the Soaring Scout with Temporary. My opponent argues the 2 runes channeled by its Deathknell are ready because of the Awaken step. Is that correct?", |
| "canonical_answer": "No. The turn phases resolve in order: (A) Awaken — all runes and units ready; (B) Beginning — Temporary triggers fire and Deathknell goes on the chain; (C) Channel — new ready rune is channeled; (D) Draw. Since the Awaken step is fully completed before the Beginning step, the 2 runes channeled by the Reflection Token's Deathknell enter exhausted. The Awaken step has already passed by the time those runes are created.", |

| "question": "If I have Consult the Past hidden and pay 1 Power to play it from facedown, does Jhin Legend's ability trigger?", |
| "canonical_answer": "No. Jhin's ability requires that you spend 4 or more Energy to play the spell. When playing Consult the Past from facedown, you spend 1 Power, not 4 Energy, so Jhin's condition is not met and his ability does not trigger.", |

| "question": "How many banish zones does the game have? Can Jhin Legend recycle a spell that banished itself, like Time Warp?", |
| "canonical_answer": "Formally, there is one banishment zone. However, the game tracks what banished each card per CR 427.3, for purposes of cards like Jhin, Cursed Sarcophagus, and Zero Drive. Jhin Legend specifically requires that the four spells were banished by him, so spells banished by other effects do not count. Whether Jhin can banish a spell that banishes itself (such as Time Warp) is an unresolved rules debate pending future clarification.", |

He reacts to the Deathknell trigger by revealing the hidden card and playing Guards!, which lets him play a Sand Soldier that uses the Battlefield Sword to kill my other sprite. Is this legal?", |
| "canonical_answer": "Yes, it is legal. You do not lose control of a battlefield while there is still a chain on the stack. When the Deathknell triggers, the opponent is still the controller of the battlefield, so hidden cards on that battlefield are not sent to the trash. He can legally react to the Deathknell trigger and play Guards! before the chain fully resolves.", |

| "canonical_answer": "Yes, it is a continuous effect that is constantly rechecked. Switcheroo takes a snapshot of current might values at the time it resolves, applying a static swap. If Yi's passive later becomes inactive (e.g. an extra defender enters, combat ends), the unit immediately loses the +2 might from Yi.
