Kato the Arm
Kato gives his current keywords and his current Might as a bonus at the moment the ability resolves. Later changes to Kato (gained keywords, Might changes) don't affect what the target unit received; it is locked in at resolution. Citaat uit de bron: “Kato gives his current keywords and additional Might equal to his current Might to the unit you choose. Later changes to Kato don't matter; what the unit gets is locked in as the ability resolves.”
Jax, Unmatched
Jax's Equipment everywhere have Quick-Draw: each gains [Reaction], meaning when you play it, you attach it to a unit you control. This is captured in the revised text. Citaat uit de bron: “Your Equipment everywhere have [Quick-Draw]. (Each gains [Reaction]. When you play it, attach it to a unit you control.)”
Janna, Savior
Janna, Savior's play trigger is revised to 'move up to one enemy unit,' making the enemy-unit selection optional. This allows her triggered ability to be placed on the chain and heal your units even when no enemy units are present at the battlefield. Citaat uit de bron: “heal your units here, then move up to one enemy unit from here to its base.”
Rell, Magnetic
Rell, Magnetic is revised to use a reflexive trigger for Equipment attachment: when she attacks and you play a qualifying Equipment for free, 'then do this:' attaches it to her as a separate chain item, allowing players to respond before the attachment resolves. Citaat uit de bron: “If you do, then do this: Attach it to me.”
Arise!
Arise! is revised to use a reflexive trigger: it first plays a 2 [M] Sand Soldier unit token for each Equipment you control, then 'Then do this:' readies up to two of them, allowing players to respond between the two effects. Citaat uit de bron: “Play a 2 [M] Sand Soldier unit token for each Equipment you control. Then do this: Ready up to two of them.”
Deflect
Deflect is a mandatory additional cost: you must pay it if you want to finalize a spell or ability that chooses a unit with Deflect. The fact that you can choose not to finalize triggered abilities (to avoid paying) does not make the cost optional. Ezreal, Prodigy cannot reduce Deflect costs. Citaat uit de bron: “Deflect is a mandatory additional cost, meaning you must pay it if you want to finalize a spell or ability that chooses something with Deflect.”
Icathian Rain
Icathian Rain is no longer a reflexive trigger. All six targets are chosen upfront before anything resolves; the opponent can react before resolution; then each chosen unit takes 2 damage on resolution. The same unit may be chosen for multiple instances. Citaat uit de bron: “you pick all the targets up front, the other player can react before any of it resolves, and then each of the units affected take the damage on resolution”
Falling Star
Falling Star is no longer a reflexive trigger. All targets are chosen upfront before anything resolves; the opponent can react before resolution; then each chosen unit takes 3 damage on resolution. The same unit may be chosen for both instances. Citaat uit de bron: “you pick all the targets up front, the other player can react before any of it resolves, and then each of the units affected take the damage on resolution”
Accelerate
Accelerate creates a delayed replacement effect that causes the card to enter ready. This delayed replacement effect persists on the card even after the Accelerate keyword itself is no longer present when the card resolves. Citaat uit de bron: “Accelerate creates a delayed replacement effect that causes Atakhan to enter ready. Although he lacks the Accelerate keyword when he resolves, he still has the delayed replacement effect”
Reckoner's Arena
Reckoner's Arena's activate effect simulates a conquer event without an actual conquer occurring. Because the card specifies units, only units with conquer effects at Reckoner's Arena see this conquer event and can potentially trigger. Citaat uit de bron: “Reckoner's Arena's case it specifies units, so only units with conquer effects at Reckoner's Arena will see this conquer event”
Elder Dragon (§460.2.c.3)
Elder Dragon's passive ('Any amount of your damage is enough to kill enemy units') alters the lethal damage threshold for units with damage marked by Elder Dragon's controller to any non-zero amount. As a result, Elder Dragon can check damage marked on units before it enters the board, and its controller need only assign one damage per unit during the Combat Damage step. Citaat uit de bron: “Elder Dragon can check damage marked on units by its controller before it enters the board, and that players need only assign one damage to units during the Combat Damage step while they control Elder”
316.5.b
Rule 316.5.b is corrected to read: 'A Showdown is marked as staged at a battlefield in the cleanup after the Contested status is applied to that battlefield.' The old wording incorrectly implied a Showdown is only staged at an uncontrolled battlefield; the corrected wording allows Showdowns to be staged while the battlefield is still controlled by a player. Citaat uit de bron: “A Showdown is marked as staged at a battlefield in the cleanup after the Contested status is applied to that battlefield.”
344.2
Rule 344.2 updated: a Showdown is opened during the Cleanup at the end of the action that caused the Battlefield to become Contested if there aren't units controlled by different players at that Battlefield — replacing the old condition of 'the Battlefield is uncontrolled when it becomes Contested.' Citaat uit de bron: “If Control of a Battlefield is Contested and there aren't units controlled by different players there, a Showdown is opened during the Cleanup at the end of the action.”
323.6
Rule 323.6 is corrected to read: 'Players lose control of any controlled Battlefields without their Units occupying them if the turn is in an open state and there is no Showdown or Combat ongoing there.' This replaces the old wording, which incorrectly made unoccupied battlefields with no Showdown or Combat become universally Uncontrolled rather than stripping control only from the player whose units are absent. Citaat uit de bron: “Players lose control of any controlled Battlefields without their Units occupying them if the turn is in an open state and there is no Showdown or Combat ongoing there.”
Draven, Vanquisher
Draven, Vanquisher reads 'When I attack or defend, you may pay [C]. If you do, …' — because 'you may pay [C]' does not fall in the expected cost-within-instructions sequence position, the resource payment is not the base cost of the triggered ability. It is paid on resolution of the ability (not during finalization) and functions as a game action checked by 'if you do', not as a cost. Citaat uit de bron: “those resources are not a cost and are paid on resolution of the ability and not finalization.”
Even when no enemy units are present during a Showdown, both players may still play Actions and Reactions in an attempt to remove the attacking units.
“Even if there are no enemy units, players may still play Actions and Reactions to try and remove the attacking units.”
A player's main deck may only contain cards belonging to the domains listed on their Champion Legend card.
“her deck must only contain cards of the Mind and Order domain”
