Deck looks fun, love to see our favorite 6/6 flying trampler back

I've been messing around with a few MB ideas and I think that there should be 4x dismembers somewhere between the main and bord, but thats me

I mentioned Phyrexian Crusader to you....DO IT.

Also, back when I played MBC all of those eons ago, I found Crystal Ball was a nice card advantage engine. I might look at running just one.

Just a thought...how would you feel about a singleton Sorin's Vengeance? Too pricey? It might be a neat trick.

Anyway, looks awesome! I can't wait to be back so I can play against this!

I would add the following to the sideboard:
1. Doomblade
2. Either Memorcide or Surgical Extraction (maybe even a split 3/1 or 2/2)
3. A Black Sun or two since Consume the meek is nice, but it limits your options, whereas -1/-1 counters play no favorites.
4. Maybe a single Consuming Vapors, so you can get that Persecutor out of there, or remove a control deck's titan of choice.
5. Additional Dismembers wouldn't hurt you, but with the other removal it isn't really needed all that much.
6. A really cool card I've seen have a lot of success too is Bloodhusk Ritualist.
7. Praetor's Grasp

Sorry that's such a wide scope, but being mono anything means you have to have answers for just about anything. With the hand disruption cards like Surgical Extraction are going to be very nice, and cards like Bloodhusk Ritualist will shine cause you're going to know exactly how much damage you're going to do. Anyways, have fun with it! Wish I could be there to see it tonight, but I was too nice a guy and covered a shift where I shouldn't have, but that's life!

Thanks for your input guys. Im going to try all those options in side bar and bring them in to see how they work. The main bored im leaving alone cause im pretty confident on my build. You guys are awesome cause you gave me a lot of stuff to work with. Thanx guys!
