Let's say I attack my opponent. They block with a champion. I play an event that will break their defending champion. At that point, does my attack directly hit my opponents life points? Or can they declare another block if they have an available champion?
When a blocking champion is declared, the attack is considered to be blocked reguardless if the blocker is removed from combat.
All blocking champions are declared at the same time. Once the defeding player ends the declare blockers phase, blockers cannot be added to combat.
Only champions with Breakthrough would deal damage to an opponent in the event of a blocked attack.
