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.”
Bone Skewer forces an opponent to play a chosen unit from their hand ignoring any and all costs — both Energy and Power — to the designated battlefield.
“They play that unit to that battlefield, ignoring any and all costs.”
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.”
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.”
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.”
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”
Recalling a unit to base via Zhonya's Hourglass is explicitly not considered a move.
“Send it to base. This isn't a move.”
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.”
Keeper of Masks has Temporary, meaning it is killed at the start of its controller's Beginning Phase before scoring occurs that phase.
“Temporary (Kill me at the start of my controller's Beginning Phase, before scoring.)”
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”
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.”
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”
Rengar - Trophy Hunter's Ambush ability can target a battlefield that contains only enemy units, bypassing the normal Ambush requirement of having friendly units at the destination.
“I can Ambush to a battlefield where there are enemy units, even if you don't have units there.”
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.”
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.”
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.”
Flow
A spell played for its Flow cost is banished even if countered by Abandon. "Then banish it" means: if the flow spell would leave the chain after becoming a finalized chain item, and leaving the chain was not instructed by the spell's own execution, banish it instead. Abandon returning the spell to hand counts as such a departure, so the spell is banished rather than returned. This also applies to effects like Kai'Sa, Evolutionary and Fizz, Trickster. Citaat uit de bron: “No matter how it happens, as long as the flow spell leaving the chain wasn't instructed by the execution of the spell itself, it will be banished.”
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”
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.”
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.”
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.”
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”
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”
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”
When Promising Future lets players play banished cards ignoring Energy costs, players must still pay Power costs on those cards.
“each player plays those cards, ignoring Energy costs. (They must still pay Power costs.)”
reflexive trigger
Reflexive triggers, identified by 'then do this:' language, create new chain items to handle effects that need to offer players a chance to react between two effects, or that must happen after the rest of a spell or ability resolves. Citaat uit de bron: “Reflexive triggers, identified by 'do this:' language, create new chain items to handle things that need to offer players a chance to react, or just need to happen later”
Janna is a Reaction that can be played in response to events at a battlefield you control, not only at enemy locations.
“Reaction (Play any time, even before spells and abilities resolve, including to a battlefield you control.)”
