This is the most consistent of my multiplayer decks, for my play group.  Once everyone sees Serra's Avengers or a bunch of plains they know what I am playing.  As they call it, my bitchy response deck.  It just sits and slowly powers out the big hitters.  If someone swings I usually have an answer to remove it, if its a group then I burn a Wing Shards, if it is a combo player I burn a Path to remove the cog.  Truthfully at this point it works because the group refuses to attack into it because the possibility I might remove their hitters.  Which gives me time to build up.  Plus it plays to my style, white aggression control.
