How do Generals work?

Each General is a unique card with a unique ability that is triggered when some conditions are met. This condition can take place right at the start of the battle, after a few seconds, when you deploy five cards, or even after dealing certain percent of damage on the enemy’s bunker. After the trigger is activated, the General’s ability (which can be the deployment of some troops or the addition of extra shields on your bunkers) will automatically take place.
