Rulings

If Seabound Immortals on both sides are killed at the same time (for example by Tidal Wave), each one joins its own player's crew.

If Asgeir has Shocking Grasp attached, it has lost its passive abilities, so it doesn't return to play when it's killed, including when it's killed in combat.

Asgeir is Unique. If a second Asgeir is killed and returns as a support ability while the first one is still in play as a support ability, the first one is destroyed and goes to the graveyard.

If Zephyra has Shocking Grasp attached, it has lost its passive abilities, so it doesn't return to play when it's killed, including when it's killed in combat.

Zephyra is Unique. If a second Zephyra is killed and returns as a support ability while the first one is still in play as a support ability, the first one is destroyed and goes to the graveyard.

An opposing ally killed on the turn it was summoned has already lost its passive abilities, so allies such as Zephyra, Winterbourne or Asgeir, Ashwalker don't return to play. An ally summoned on an earlier turn keeps its passives and returns as usual, for example Eternal Troll.

Skyborne's exile can't hit allies with Steadfast. If the only opposing ally costing 2 or less has Steadfast (such as Stardust Transfuser), the exile can't be chosen. If there are other opposing allies costing 2 or less, one of those is exiled instead.

While it's damaged, Towering Brute can't be targeted by Krugal Butcher's summon ability, even if it is also disabled or poisoned.

Krugal Butcher can't kill a damaged Towering Brute, even if the Brute is disabled or poisoned, because a damaged Towering Brute can't be targeted by abilities of opposing allies. Any other poisoned or disabled ally is a valid target.

Only weapons you summon lose durability. Weapons your opponent summons are not affected.

Only a ship you control counts. An opponent's ship doesn't make your items and abilities cheaper.

If the opponent controls Lyra Blackrose, the ability you discard to pay for Moment of Acquiescence's 0SE is discarded first, and Lyra's random discard is then made from the rest of your hand. The same card can't be discarded twice.

When an ability is activated by discarding a card as its cost (such as Moment of Acquiescence's 0SE), that card is discarded first. Lyra Blackrose's random discard can't pick the same card a second time.

Health your hero or allies recovered earlier in the turn counts toward the 3, even if it was before Zails Fragrance was played. Recovering only 2 health doesn't trigger it.

Only damage your hero deals to allies counts toward the 5 damage. Damage your hero deals to the opposing hero doesn't count, and neither does damage dealt by your allies.

Golden Katar loses no durability when your hero defends, but it still loses 1 durability each time your hero attacks with it.

Only the first time Wyvern Mail is used in combat each turn is free. If your hero is attacked again in the same turn, the armor still reduces the damage by its defense, and it loses 1 durability as usual.

Molton Giant's Axe also ignores damage reduction from armor abilities, not just an armor's defense. An ally protected by Celestial Armor's "all damage is reduced to 0" still takes the axe's full damage.

Damage increases are applied before armor reduces the damage. For example, a 1-attack electric ally attacking an opposing hero wearing 1-defense armor (such as Wrath of the Forest) still deals 1 damage: Voltar's Ring adds 1, then the armor removes 1.
