Forum:Blackwing Armoured Master

Hi,

Part of the synchro Blackwing Armoured Master's effect is that it cannot be destroyed by battle and you take no battle damage from battles involving this card. But what if it attacks an oppenents monster whose effect is that whatever monster attacks it, the attack of the attacking monster is deducted from the attacking players life points. Would that still apply for Blackwing Armoured Master or will its effect protect it?
