SB: 1  Hokori, Dust Drinker

This deck can be quite evil and it can have some pretty explosive starts. I'm trying to make it into a sort of EDH armageddon stax. Any tips to optimize it, make it better? There are so many viable cards to put in, I am overwhelmed. This deck had 200 cards and I've had to cut down quite a lot. The big bombs tend to be the armageddon effects or just waiting for the opponent to tap out and lock him out with Hokori. I also love the white counterspells; nobody EVER expects them.

My best advice to you would be to not play this deck, unless of course you want the people you're playing with to hate you.

If you insist on torturing people, you could consider Winter Orb, Static Orb, Storage Matrix, Rishadan Port, Mishra's Helix

Seems like it would be perfectly fine for duels, but would be sufficiently irritating to warrant your immediate messy execution in proper multiplayer gaming.

Our playgroup tends to have a Zur a Sharuum, a Rofellos, Azami, really annoying storm combo.... we're all a bunch of spikes. Usually they've got bigger fish to fry than me since I tend to be slower than them to set up.

I've found it to be the other way around, this deck can be very frustrating to play against in a duel, but in multiplayer its not so bad since you can only keep one guy at the most locked down effectively.

[Tabasco]

You could play Darksteel Reactor as a wn condish that no one can deal with since they are all locked down.

I see no reason not to run Tithe or Gift of Estates.  If you're running Land Tax, Wayfarer and Knight of the White Orchard, these are pretty swell, too.  And if you really wanted to, you could run the ole Parfait engine of Scroll Rack.
