What my problem is when last night a Stuffy Doll blocked my 11/11 trampler, the result was me taking 11 damage and Stuffy Doll absorbing one of that damage from the defending player who took ten damage. We called mtg for a ruling and that was the one given. How is it that Stuffy Doll takes 11 damage, but at the same time ten of it gets through to opponent? I was expecting to take one damage from Stuffy Doll, seeing as how Stuffy Doll only really took one. I don't understand that in one case Stuffy Doll has taken one and in the other Stuffy Doll has taken 11. Sounds like a logical fallacy ie 1 = 11.
Second question is what if I block an 11/11 trampler with a Phyrexian Obliterator ? Will the opponent have to sacrifice 5 permanents or 11 permanents? Would it be any different if the attacking creature didn't have trample?
