I am sure all you Commanderers are keeping a close eye on the spoilers, but if not, check out http://www.gatheringmagic.com/commander-previews-68/
The cards spoiled this time are pretty cool, but the main card I want to focus on is Stranglehold. Stranglehold is a 3R enchantment that reads- Opponents can't search their libraries and if an opponent would begin an extra turn, skip it instead. Red really needed this card and it will splash extremely well. I expect to see this card frequently. This card is a good omen for the rest of the unspoiled cards in the Commander boxes- it outright hoses the most abusable mechanics of the format. Sure its not instant speed like Aven Mindcensor but as an enchantment is has less of a chance of being hated out. It may even be a valuable political tool against a blue combo deck or an abusive Sisay build. Monoblack builds fear this card.
I will end this post with the flavor text on Stranglehold- "The correct answer to a barbarian's riddle is to choke on your cleverness and die."
