I don't think that anyone disagrees that standard OU is a more competitive tier than DW OU, so disagreeing to disagree is pointless.
I completely disagree with that statement. Where are you getting the facts that you are basing your claims off of?
To stay on topic, I think Keldeo is really a force to be reckoned with and you cannot ignore it when teambuilding. Many of the checks to the CM set are destroyed by the Specs set, so you have to play really carefully if you see Keldeo on the opponent's team. Has anyone experimented with a Scarf set?
