Hello, I'd like some advice on my black and red land destruction deck. Any advice would be appreciated, including fun cards to put in, or pointing out cards that don't fit. This is just for friendly casual play, but I might be interested in tournaments if it qualifies. This is the first deck I've built on my own, and I hardly ever win against my friends--and if I do it's usually due to the fact they got a bad shuffle or bad luck. I have only won once in the past several months and I play several times a week, it's getting pretty old.
My idea is to delay my opponent long enough by destroying any lands he or she gets out early, so they can't play anything while I build my field and wait for my high-cost cards, and Westvale Abbey or It that betrays to come out and swing hard. The problem I've run into is that I haven't once been able to work up the mana necessary to get It That Betrays out, and the few times I got Westvale Abbey to transform it was immediately exiled or taken control of against me, and I didn't have any other "big hurrah" ready to win after that.
The rats and Nighthawks are there for the deathtouch, to deter possible early attacks, plus the Nighthawks have lifelink. Emrakul's Hatcher are there for the spawns to help get Westvale Abbey transformed and to block. Charmbreaker Devils and Goblin Dark-Dwellers are there to keep recasting those land-destruction sorceries.
I like the Void Winnower because it's cheaper than It That Betrays and has a fun ability. A friend's newly-built mono-black discard deck laid waste to me last night, so I started looking at the Surgical Extraction and Imp's Mischief.
