I do love me some multiplayer EDH, and the closest thing to it online is the Commander format. The R/B deck I've been playing has shifted somewhat. I've played this deck numerous times on MtGO and have only lost once.

What I like about the deck is the unpredictability. You never really know what you're going to get. You can usually defend yourself until you drop Kaervek, but the deck is capable of just going aggro as well. Kaervek is usually less scary to your opponents than your enchantments - that's where the real firepower is. Dropping Kaervek is a threat, but he's generally not a table-turns-on-you threat, and can be used quite politically to help other players. Then all you need to do is mop up.
