Profiteer
A player can use Profiteer to disempower their own legend (e.g., Ambessa, Matriarch of War) in order to empower another unit such as Kayle. A player controls their own legend; control of legends cannot change. Citaat uit de bron: “you can disempower Ambessa, Matriarch of War with Profiteer. And yes, you control your own legend.”
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”
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.”
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.”
Tianna Crownguard
Tianna Crownguard only prevents opponents from gaining points; she does not interfere with the process of conquering or holding battlefields. Opponents can still conquer and hold battlefields, receive conquer/hold triggers, and even draw a card if conquering a final point they cannot score. Citaat uit de bron: “Tianna is solely concerned with points and doesn't interfere with the process of conquering or holding battlefields.”
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”
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.”
Yone, Blademaster
Yone's ability checks the control status of the battlefield immediately before he conquers it. He triggers at the end of a noncombat showdown in which he conquers an uncontrolled battlefield. He also triggers in 'surprise defense' scenarios where units move during a showdown and he ends up defending a battlefield he doesn't control—if he conquers it, the battlefield was uncontrolled before he conquered it. Citaat uit de bron: “We're tweaking his text to cue off the control status of the battlefield immediately before conquering it.”
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.”
Legion (§419.4.b)
Legion checks whether cards were finalized by an opponent, not whether an opponent controls a spell that resolves. A spell finalized by an opponent but subsequently taken over via Rebuttal still counts as finalized by the opponent, so Legion abilities remain active. Citaat uit de bron: “Battering Ram and Legion … check whether cards were finalized. Although you gained control of Stupefy, you did not finalize it; you got it after it was already finalized by your opponent.”
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.”
Cruel Patron (187.4.c example) (§187.4.c)
If a player kills their only unit at a battlefield to pay Cruel Patron's additional cost, a cleanup is triggered, but control of the battlefield is not lost because Cruel Patron is on the chain. The player may then choose to play Cruel Patron to that same battlefield. Citaat uit de bron: “because there is an item on the chain (Cruel Patron) I don't lose control of the battlefield”
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.”
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”
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”
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”
Recalling a unit to base via Zhonya's Hourglass is explicitly not considered a move.
“Send it to base. This isn't a move.”
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.”
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.”
Iascylla (§359.3.f.1.)
Iascylla's delayed trigger references the battlefield she held at the time her trigger condition fired, not at resolution. When a triggered ability references information implicit in its trigger condition, that information is captured when the ability triggers. Citaat uit de bron: “Iascylla's delayed trigger refers to the battlefield that she held.”
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.”
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”
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.”
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.”
battlefield control without units
When a player controls the battlefield but has no units there (achievable via Hostile Takeover or Stormbringer), the current rules have a gap with no obvious outcome. The interim ruling is to start a noncombat showdown as the least disruptive way to handle this scenario. Citaat uit de bron: “starting a noncombat showdown is the least disruptive way to handle this scenario”
Baron Nashor (§054.2., 369.3.)
Baron Nashor's passive generates a delayed replacement effect ('I enter there') that replaces his entering any other location with entering the Baron Pit, bypassing play-location restrictions such as Mageseeker Warden. Dragon Roost is only a permission on play location, not a replacement effect, and therefore cannot bypass such restrictions. Citaat uit de bron: “Baron Nashor's passive ability generates a delayed replacement effect...This replacement effect replaces the event of him entering to any other location with him entering to the Baron Pit.”
Weaponmaster
Weaponmaster as a keyword is always optional. It is always a choice whether or not to use this play ability. The reminder text ('You may') is more accurate than the Core Rules wording, which implies a mandatory target; the Core Rules language will be cleaned up in the future. Citaat uit de bron: “Weaponmaster as a keyword is always meant to be optional... It is always a choice on whether or not to use this play ability”
Forgotten Monument
Forgotten Monument completely prevents the process of scoring at its battlefield, meaning no conquer triggers, no hold triggers, and no points from those activities. This differs from Tianna Crownguard, who only blocks gaining points. Extra points from other sources (e.g., Renata Glasc, Mastermind) are unaffected. You can still gain control of the battlefield after a showdown—you just cannot conquer it. Citaat uit de bron: “Forgotten Monument completely prevents the process of scoring there. That means no conquer triggers, no hold triggers, and no points from doing those things.”
Draven, Audacious
When Draven wins combat and conquers, his triggered ability resolves before you gain the regular point for scoring the battlefield and before any conquer effects trigger. Consequently, Draven's point is counted first—e.g., going from 6 to 7 points means the subsequent conquer gives a card draw instead of the 8th point. Citaat uit de bron: “Draven's ability will trigger and resolve before you gain your regular point for scoring the battlefield and before any conquer effects are triggered.”
