Forum:Brron Mad King Q

Brron, Mad King of Dark World's effect states that: When this card inflicts battle damage to your opponent's life points, you can select one card in your hand and discard it to the graveyard.

My friend plays waboku when my Brron attacks him directly. He says because his life points have not decreased then I have not inflicted battle damage so I cannot use my effect. My argument is that I HAVE inflicted battle damage but the damage is 0. He has not negated my attack he has just reduced the damaged to 0 thus I have inflicted 0 battle damage and my effect goes off.
