Blow Your Trumpets, Gabriel

Gosh darnit, didn't mean to just post that, sorry. I'd recommend taking out Hissing miasma, blind hunter and mourning thrulls/perilous myrs for DeathBringer lieges and Tidehollow scullers. I have a similar deck that works pretty well and it's really fun, if you want any advice. http://tappedout.net/mtg-decks/blow-your-trumpets-gabriel-2/

I think I will go ahead and switch the Myrs for some Tidehollow Sculler , but I don't want to have too many 5-drops in this deck so the Liege might sit out on this one. The other small creatures all fit the theme of me either gaining life or hurting the opponent if they attack, so I'll keep them in. Hissing Miasma is really good in multiples, and it's the card that normally pushes me ahead in multiplayer since nobody attacks into it while other players are still in the game. I find that it's normally the nail in the coffin, as people can use creature removal for Souls of the Faultless or attack with a single fatty through Hissing Miasma , but it's having both out that keeps most creature decks at bay long enough for me to find a bomb and go to town.

Okay, it seems really funny in multiplayer/casual, and the Scullers will be really good in there, they do a lot :P

you should look at Exsanguinate my black multiplayer deck abuses it to great effect. also Promise of Power is great with loads of lifegain

The problem with both of those cards is that they take a lot of mana to work effectively. I find that with my current land count it's sometimes hard just to get up to 5 mana to cast Obzedat, and I want to keep my life so Divinity of Pride stays large, so I don't think either one would help my deck without extra support (ie- some form of mana-ramp),
