Now you don't have to wait for your opponent to respond to your challenge. The Tournament now features the automatic response system.
When you challenge someone in the Tournament, the game records your moves (gem matches, whether you used spells and/or boosts, auras, special attacks). Auras in the automatic response are a sum of the auras at the moment of recording that response and the auras at the moment of using that response in defense. When you complete a match in the Tournament, you get a Protection point which represents that recording.
When someone challenges you, the game generates a copy of your character which uses the moves from the recording mentioned above. Spells and boosts are taken from the Arsenal. Each recording is only used once.
What if I don't challenge anyone in the Tournament?
If you don't challenge anyone, the game will use the default response when someone attacks you. The default response is an equivalent of a simple 3-gem match without boosts, spells, auras or special attacks.
