I was playing Commander with a group of friends, and I run Angus Mackenzie as my commander for this deck I was using. I had Azor's Elocutorson the field with some other cards, but importantly I had Platinum Emperion on the field as well.I was attacked by one of my of my opponents and let the attack go through, but with Platinum Emperion's effect my life doesn't change, my friends assured me that even though I didn't lose life due to the effect that it still counts as damage and Azor's Elocutors loses a counter because of that. Since my life total didn't change, and even though attacking creature went through and still still hit me, does it still count as damage in this situation, and I still remove a counter from Azor's Elocutors?
1/1/2011 The ability doesn't prevent damage. Rather, it changes the results of that damage. For example, if a creature with lifelink deals damage to you, you won't lose any life, but its controller will still gain that much life. Similarly, if a creature you control with lifelink deals damage to another player, that player will lose life but you won't gain any life. Notably, if a creature with infect deals damage to you, you'll get that many poison counters.
1/1/2011 Abilities that trigger whenever damage is dealt to you will still trigger because that damage is still dealt, even though your life total doesn't change as a result.
So you take damage and any effects that trigger as part of that occur.
Yes. You were still dealt damage. So, you would still get Poison counters if the source had Infect, you would still track Commander Damage if you were damaged by a Commander, the source's controller would still gain life if the source had lifelink, and so on. Platinum Emperion does not prevent damage. It just changes the result of that damage but the damage is still dealt.
So you take damage and any effects that trigger as part of that occur.
