Silence all enemy units.
Your units get
Charge,
Deadly,
Endurance, and
Overwhelm this turn.
Card sounds may differ from in-game as they get updated.
Charge - Can attack the turn they are played.
Deadly - Units and spells with Deadly kill any unit they damage, regardless of health. For example, a 1/1 with Deadly can kill a 5/5 attacker.
Endurance - Units with Endurance ready at the start of each players turn, so they can attack and still be ready to block during the enemy turn. Additionally, they are completely immune to enemy stun and exhaust effects.
Overwhelm - A unit or spell with Overwhelm will deal any excess damage to your opponent on your turn (does not work while blocking).
Silence - Remove all text from a card and its attachments.
