Okay, I've only been playing for about a month and this is the deck that I constructed using the Vamparism premade deck. I have played one tornament but I haven't used this deck in particular there. Any feed back would be nice and help out a lot. I'm willing to add cards and not take out some but the highest deck I am willing to play is a 65 card deck.
I forgot to mention, I'm going to be taking the Ruthless Cullbladess out once I get another Blood Seeker and two more Guul Draz Vampires.
Get a haircut.
I hate dogs.
