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.”
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.”
Mel, Newly Awakened (§375.)
When Stupefy (give -1M, minimum 1M) is cast while an empowered Mel, Newly Awakened is in play, Mel's replacement effect changes the -1M to -2M, but the replaced event inherits Stupefy's "to a minimum of 1M" modifier. A replacement effect inherits any modifications applied by the game effect that generated the replaced event, so a 2M unit becomes 1M. Citaat uit de bron: “a replacement effect that replaces an event modified by the game effect that generated that event will inherit any of those modifications”
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.”
combat (§465.2.c.4.a)
Damage-increasing replacement effects now also apply during damage assignment, in addition to prevention effects (such as Ki Barrier or Counterstrike) that already applied at that step. Citaat uit de bron: “damage increasing replacement effects will also apply during damage assignment”
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.”
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.”
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”
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”
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.”
Zilean + Deceiver (no infinite token loop)
When Deceiver's reflexive trigger copies Zilean, Time Mage, the two Reflection tokens resolve and become copies of Zilean. However, there is no subsequent 'play token' game action for Zilean's replacement effect to apply to, so no further tokens are produced and the loop does not repeat. Citaat uit de bron: “there is no subsequent play game action involving tokens to apply their replacement effects to”
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”
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”
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.”
Brush – Swap Back (§438.1)
When a Brush token is swapped back, the Brush token ceases to exist. A player can choose to swap back to any object that was replaced, including the original battlefield, because a replacing game object inherits all statuses and conditions of the game object it replaced (438.1). Citaat uit de bron: “The Brush token will cease to exist. When swapping back, a player can choose to swap back to any object that was replaced, including the original battlefield.”
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.”
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”
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”
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”
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.”
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.”
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.”
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”
Rebuttal
When Rebuttal resolves and the new controller pays A, they may remake any number of targets or modes; choices not remade must still be legal. If no new choices are made at all, all current choices (legal or not) remain unchanged. Spell rules about valid choice locations (e.g., face-down play restrictions) apply regardless of who controls the spell when new choices are made. Citaat uit de bron: “You can choose any number of targets or modes to make new choices for. The rest remain the same. If you are remaking choices... any choices you choose not to remake must be legal choices.”
Contested Status (§323.8)
When a player moves a unit to a battlefield they don't control, the Contested status is applied to that battlefield immediately upon the unit becoming located there — regardless of whether units controlled by another player are present. Per rule 323.8, a Showdown is then staged at that battlefield in the following cleanup. Citaat uit de bron: “apply the Contested status to that battlefield immediately upon becoming located there, regardless of whether there are units controlled by another player there or not.”
Counter Strike vs. Elder Dragon (§437.2.a)
If Counter Strike (or any prevent effect) completely prevents Elder Dragon's 1 damage to a unit, that damage is never dealt per rule 437.2.a. Since no damage is dealt, Elder Dragon's passive ability—which redefines lethal damage thresholds for units that have damage marked on them by its controller—has no opportunity to apply to that unit. Citaat uit de bron: “If the damage is entirely prevented, it is never dealt per rule 437.2.a., and thus there is no opportunity for the passive ability of Elder Dragon to apply”
