MTG: Road to Nationals (Decktest #1)

Wsssup .. my Road to Valencia has ended sadly for me. Now ... its time for Road to Nationals. With the Nationals Qualifiers coming this August 19, 2007, its time again for me to practice my standard deck. I will be using U/B Dralnu (without Dralnu).

Tried this decklist with some frens over at Comics Corner. Mostly tested out with Rakdos deck. Sometime I win and sometimes I loss. Tombstalker is the game winner for my deck. The only thing i did not find usefulness are Brine Elemental and Vesuvan Shapeshifter. Most prolly I will replace it with more Damnation and Extirpate. I also find that the single signet is not worthy in the deck as well, im still thinking of what to replace it with ... whats on my mind is either extra Repeal or Cancel. I need all the counterspells i can get. The current meta got Nats Qualifiers, if im not mistaken .. will be Blink variants and Rakdos decks.
