Battlecry
From Liquipedia Hearthstone Wiki
Battlecry is an ability which performs the description when the card is played from your hand. It will for example not work when you swap a card on the board with one in your hand nor if you copy a minion from your opponent.
Interactions[edit]
Battlecries take priority over secrets. If, for example, one player plays a battlecry and his opponent has a Snipe active, the battlecry will still occur before the secret triggers and deals damage.
Battlecries only happen when you physically play the card from your hand. For example, if you play a battlecry minion using Mindgames then the battlecry will not occur.
