...have you considered making this an EDH? because you're pretty close with so many one-ofs.
Got to many creatures, and you don't seem to have well of a strategi exept playing creatures, do like BlckGaming says and make a Demonic EDH Deck instead.
lol The Great Blood Cult there's some ideas. I love seeing demon EDH's. This could do it.
how does it look now too a while for me to get it the way i wanted it. so its alot better to play with now.?
