Board space

Board space refers to the number of available slots for cards to remain in play at a time. There are three areas where cards can remain in play: the board, where minions and locations exist; the hero zone, where certain spells exist; and the weapon slot (opposite to the Hero Power), where weapons exist.

Each player is allowed seven minions and locations, a combination of five hero zone cards, and one weapon.

Notes

General

• Cards that summon or cast "all" of something, such as Mysterious Challenger or N'Zoth, the Corruptor, will only summon until that respective part of the board is full.

Board entities

• Board entities represent minions, locations, and permanents.
• Minions and locations cannot be played from hand when a player's board is full, nor can spells that merely summon them.
  • Spells that summon minions in addition to other effects can be played.
• If a minion would be summoned but the board is full, nothing happens. It will neither enter play nor be destroyed.
• Using a Mind control effect such as Shadow Madness, Mind Control Tech, or Sylvanas Windrunner when you have a full board kills the minion instead of taking it. Playing a mind control spell with six minions on your board, one of which summons a minion "whenever you cast a spell," such as Violet Teacher, causes the triggered friendly minion to summon a minion, after which the enemy minion targeted by your spell dies.
• A Magnetic minion can be magnetized to another minion even on a full board. This will shift the board entities slightly, making room for an 8th minion momentarily until the Magnetic minion is Magnetized.
• Minions can appear to occupy more than seven spaces while processing long animations, such as multiple Shudderwocks with summoning Battlecries played quickly in the same turn. This is purely visual - any extra minions are not actually in play yet and cannot be affected by any cards.

Spells

• You can only have five cards with hero zone effects active at a time, with specific restrictions:
  • Only one Quest or Questline.
  • Only one copy of a specific Secret or Sidequest.
  • Any number of copies of any other type of hero zone card.
  • If a duplicate spell is forced into play by cards such as Archmage Vargoth or Zul'jin, it will be revealed to your opponent but not enter play. In the case of Unseen Saboteur, it will also be removed from the hand.

Weapons

• Equipping a weapon while you have one equipped already will destroy the currently-equipped weapon, triggering its Deathrattle and replacing it with the newly played card.
