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.)”
Gear cards enter play in the Ready state (not Exhausted), so they can be used immediately; Gear always enters at the controller's Base.
“Gear cannot hold or conquer battlefields, and can only exist in base. If a Gear card is played at a battlefield, it is immediately recalled to the base.”
“Gear enters play Ready, so you can use it right away. It always goes to your Base.”
Jhin, Meticulous Killer + countered spell (Singularity)
Jhin checks whether energy was spent to play a spell and whether it became a Finalized Chain Item—not whether it resolved. If Singularity is countered after being finalized, the energy was spent and Jhin's C cost condition is satisfied, allowing Jhin to be played for C that turn. Citaat uit de bron: “Jhin checks the energy spent to play a spell, not whether that spell resolved.”
Units with the Ganking ability may move directly from one Battlefield to another, whereas normal units can only move between their controller's Base and a Battlefield.
“only units with the Ganking ability may move between battlefields”
“Some units have Ganking though, which lets them move from Battlefield to Battlefield.”
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”
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”
“You can only put cards in your deck that match your Legend's Domains”
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.”
Action Spells may be played during the controller's turn or during a Showdown; on an opponent's turn, a player may only play Action Spells during Showdowns.
“Most Spells are labeled Action, which means you can play them during your turn or during a Showdown. If it's not your turn, you can only play Action Spells during Showdowns.”
Heimerdinger, Inventor (§727.1.b.1)
Heimerdinger, Inventor can gain Jayce, Defender of Tomorrow's Empowered> activated ability (ready 2 gear) even if Jayce is not empowered, because a dependent ability exists on the card for reference and evaluation before its condition is met (rule 727.1.b.1.). Heimerdinger himself must be empowered to satisfy the ability's activation condition. Citaat uit de bron: “The Dependent Ability is present on the card for the sake of reference or evaluation until the Condition is met … Heimerdinger, Inventor is exactly one such effect.”
Each Battlefield can only award 1 point per turn; moving a unit away and replacing it with another unit in the same turn does not grant additional points.
“Moving away from a battlefield and back to it with another unit the same turn will not gain you a bonus point.”
“Each Battlefield only gives you 1 point per turn max. You can't move a unit away and move a new one in to score twice.”
Astral Heron
Astral Heron's triggered ability discounts the next card played (added to the chain and queued for finalization) this turn after the ability resolves. Erratum wording: 'When you play your first card each turn, if I'm at a battlefield, the next card you play this turn costs [2]AA less.' Citaat uit de bron: “It discounts the next card played (added to the chain and queued for finalization) this turn after the ability resolves.”
During the Beginning Phase, each player channels 2 Runes from the top of their Rune Deck; the second player channels 3 Runes on their very first turn to compensate for going second.
“If you're going second on your very first turn, you get 3 Runes instead to help catch up.”
Shady Spectacles
If a Sand Soldier equipped with Shady Spectacles (copying Azir, Ascendent) uses the copied activated ability, and then Shady Spectacles is detached and reattached to that same Sand Soldier copying the same unit, the activated ability can be used again. Each attach creates a new, distinct instance of the copied ability, even on the same game object. Citaat uit de bron: “Each instance of the copied ability is a different ability... the copied rules text is an entirely new instance of the ability.”
When an Attacker destroys all Defending units and still has units remaining, they conquer the Battlefield and immediately score 1 point; additionally, every time a Battlefield is conquered without winning the game, the conquering player draws a card.
“every time you conquer a Battlefield but it doesn't win you the game, you get to draw a card”
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.”
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.”
Rumble, Hotheaded
Rumble, Hotheaded can choose a Mech token to recycle. Tokens inherit the recycle destination of their type—a token that is a unit or gear is recycled to the Main Deck. The token then vanishes (as tokens do whenever they leave the board), but it still counts as 'the unit you recycled,' so Rumble can check its Might. Citaat uit de bron: “tokens 'inherit' the recycle destination of their type(s), so a token that's a unit or gear is recycled to your Main Deck… it still counts as 'the unit you recycled' and Rumble can check its Might.”
A unit's Might value represents both the damage it deals in combat and the total damage it can absorb before being destroyed.
“Might... this number shows how much damage they deal AND how much they can take”
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.”
Ravenborn Tome's Bonus Damage effect now applies only to the next spell played 'this turn,' preventing the bonus from carrying forward to future turns.
“The next spell you play this turn deals 1 Bonus Damage.”
Dragon Form
Dragon Form sets a unit's base Might to 5 via the Trait-Altering layer; existing arithmetic modifiers (e.g., Stupefy's -1) are applied in the Arithmetic layer. Layer evaluation is instantaneous—there is no window where the unit momentarily exists at 5 Might before the modifier is applied. A unit under both Dragon Form and Stupefy is immediately 4 Might; Fiora, Grand Duelist will not trigger. Citaat uit de bron: “this process happens instantaneously; there is no window while evaluating layers for the unit to see itself become 5 M and then go down to 4 M”
Signature Cards are Legend-specific cards that can only be included in a deck matching their designated Legend, with a maximum of 3 total Signature Cards permitted across the entire deck.
“You can only use them with their matching Legend, and you can't put more than 3 total Signature Cards in your deck.”
play from deck (banish first)
Cards that instruct you to play a card from your Main Deck must first banish that card, then play it from banish. This gives the game a defined zone for the card while it is being played and a place to return it if it cannot be played for any reason. This applies to Rek'Sai Swarm Queen, Void Burrower, Void Rush, and Reinforce. Citaat uit de bron: “banishing the card ensures that the game has a place to put the card until it's actually played, and a place to send the card back to if it can't be played”
Recalling a unit to base via Zhonya's Hourglass is explicitly not considered a move.
“Send it to base. This isn't a move.”
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”
Blood Rush
Blood Rush was printed without 'this turn' in its effect. The Assault 2 bonus it grants a unit is temporary and lasts only this turn, matching design intent and the pattern of Convergent Mutation. Citaat uit de bron: “the phrase 'this turn' was accidentally omitted … Give a unit Assault 2 this turn.”
[A] symbol
The symbol A means 'one power of any domain/color' in card text. Citaat uit de bron: “A means "one power of any domain/colorˮ”
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”
cleanup
Cleanups work inversely to other HOT FEPR procedures: several tasks are queued at once, and all of them must be completed before the FEPR process will initiate. Citaat uit de bron: “cleanups work in the inverse, where several tasks are queued at once and all must be completed before the FEPR process will initiate”
Baited Hook (187.4.c example) (§187.4.c)
When Baited Hook resolves, kills the targeted unit (the sole unit at a battlefield), and the player plays a unit from the top 5 cards, that unit goes pending on the chain. The outstanding cleanup cannot strip battlefield control while a chain item is pending, so the finalized unit can be played to the same battlefield where the kill occurred. Citaat uit de bron: “I can't lose control of the battlefield because the played unit is on the chain pending”
