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.”
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”
Dragon Roost (§054.2., 369.3.)
When two mandatory positive requirements conflict on where to play a unit (e.g., Elder Dragon's AA instructing play to Dragon Roost and another effect specifying a different location), the player chooses one requirement and ignores all others. This only applies to mandatory positive requirements that specify a location or method without also preventing play elsewhere. Citaat uit de bron: “the player chooses one of those requirements and ignores all others”
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.”
Target – 'must' be taken actions exclusion (Sigil of the Storm)
Units that use the 'must' wording (like Sigil of the Storm) are excluded from targeting. This category exists to allow cards to require something to happen and ensure it actually does, without making those objects targets. Citaat uit de bron: “Actions that 'must' be taken are a new category to handle cards like Sigil of the Storm… its purpose is to make sure that we can make cards that require something to happen and make sure it actually d”
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.”
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”
Recalling a unit to base via Zhonya's Hourglass is explicitly not considered a move.
“Send it to base. This isn't a move.”
Cards that Reduce Might
Origins cards with the 'to a minimum of 1' clause (e.g., Stupefy) retain that floor and are not receiving errata. The removal of 'minimum of 1' is a design philosophy change beginning with Spiritforged; it does not retroactively change Origins cards. Citaat uit de bron: “This is a change to our design philosophy beginning with Spiritforged, but Origins cards will maintain their functionality.”
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.”
HOT FEPR – recursive
HOT FEPR is recursive: the procedures that designate tasks as outstanding are themselves steps or substeps that wait until all outstanding tasks and all chain items are completed before moving on. Citaat uit de bron: “the procedures which designate tasks as outstanding are themselves steps or substeps. Anytime the Core Rules Document says 'the following task(s) become outstanding,' that step itself waits”
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.”
Target – you and you alone choose (other players' choices excluded)
If another player is involved in the choice, the object is not a target. Cull the Weak has no targets because all players are instructed to choose and kill a unit — the choice is not made by you alone. Citaat uit de bron: “Cull the Weak doesn't have any targets, because you're instructed to kill a unit as part of an instruction for all players to choose and kill a unit.”
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.”
Heisho, Shell of the World (§766., 767.)
While a spell or ability has at least one target that is a unit located at Heisho, Shell of the World, all instances of Deflect on all units are treated as inactive when paying costs for that spell or ability. This applies only to that specific spell or ability instance; a subsequent spell or ability targeting units not at Heisho must still pay for Deflect normally. Citaat uit de bron: “While your spell or ability chooses a unit at Heisho, Shell of the World, you ignore deflect while paying for the spell.”
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.”
Swain, Visionary
Swain, Visionary's conquest ability scores 1 extra point by checking whether you've played a non-token unit, a non-token gear, and a spell this turn. These three conditions can be satisfied by different cards; a single card satisfies only its own types. Citaat uit de bron: “Swain only checks whether you've played a non-token unit, a non-token gear, and a spell. Checks like that do not care whether they were satisfied by multiple cards or a single card.”
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”
Repeat
Repeat causes you to repeat execution of a spell's 'instructions,' which are the things the spell tells you to do as it resolves. It does not repeat costs or cost reductions—only the resolution instructions. Citaat uit de bron: “Repeat causes you to repeat execution of a spell's 'instructions,' which are the things the spell tells you to do as it resolves”
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.”
Gangplank, Naval (§477.3.b)
If Stupefy is played on an empowered Gangplank, Naval who has exactly 1M, the -M value snapshots to -0M, meaning no actual -M event is generated. With no suitable event to replace, Gangplank's replacement effect does not trigger. Citaat uit de bron: “In the case of Stupefy played on a 1 M unit, no -M is given; it is snapshot to -0 M. Thus, there is no suitable event for Gangplank's replacement effect to replace.”
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”
Glasc Mixologist (Deathknell, Unleashed update) (§187.4.c)
As of the Unleashed rules update, when Glasc Mixologist dies alone at a battlefield it controls, the unit from its Deathknell can be played to that same battlefield regardless of whether Combat is occurring. Previously this was only possible during an active Combat. Citaat uit de bron: “whenever Glasc Mixologist dies alone at a battlefield with the same controller, regardless of if there is a Combat there or not.”
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.”
Repulse vs Alpha Strike (targeting arrow count)
Repulse counts all targeting relationships ('arrows') pointing from a spell to friendly units, regardless of whether those targets currently meet the spell's targeting restrictions. Units moved to base by Flash are still targeted by Alpha Strike (arrows are 'grayed out' but present), so Repulse counts them and cannot counter Alpha Strike unless all remaining targeted units have moved to a non-board zone. Citaat uit de bron: “Repulse cares about the number of those arrows that point to friendly units, not the color of the arrows.”
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.”
Svellsongur (§369.1.)
Attaching Svellsongur to Aphelios will NOT cause Aphelios to trigger twice—correcting the previous Spiritforged FAQ ruling. Because the attach event resolves before Svellsongur copies effect text, Svellsongur does not have the copied ability at the time of attachment, so Aphelios's triggered ability cannot see a second attach event. Citaat uit de bron: “the answer in the Spiritforged FAQ is no longer true: if you attach Svellsongur to Aphelios, he will not trigger twice.”
Spinning Axe (Temporary while attached) (§816.2.a)
When Spinning Axe is attached to a unit, its printed rules text—including its printed Temporary keyword—becomes inactive. If Spinning Axe is separately granted Temporary, only that granted instance is active. Because only one active instance exists, rule 816.2.a does not prevent it from triggering; the inactive printed Temporary is treated as if it did not exist. Citaat uit de bron: “the grey Temporary doesn't have any function. We can treat it as if it didn't exist for the purposes of rule 816.2.a.”
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”
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.”
