Three of the new EDH commanders were spoiled last night.
1) Vish Kal, Blood Arbiter. This is a big, giant, scary guy. Flying and lifelink are always a potent combination period. But the two abilities makes the card even more interesting. Not exactly creature removal, more like a repeatable Innocent Blood. And there's no way to stock-pile counters so you may end up wasting a few if something small really needs to be blown up. Suited to a very aggressive style of play, this Commander is going to get blown up in so many different ways during the average EDH game.
2) Skullbriar. I like that he is an elemental. Anyone who already has a Horde of Notions deck will be lining up to add this card. I get a hearty chuckle building up deep down in my belly just thinking about it. What other kinds of counters would you want to put on Skullbriar? Divinity counters, it has been suggested. Otherwise Skullbriar is going be blown up again and again (but at least he keeps his counters!) Who is Skullbriar's arch-nemesis? Giant Oyster.
3) Edric, Spymaster of Trest. This is my favorite. Some might call him a "group hug" general, but rather Edric is actually more of a "group slug" general. He encourages all your opponents to attack, as long as they are not attacking you! Of course you get to attack and draw cards, too. In addition, I don't see this card being high on people's radar for removal, either. I'm taking a stand…Edric is the best one of these generals by far.
