I would have you seriously consider removing the Hauberk's and Ghoulcaller's from the deck. If you really want to keep the hauberk's, I would at least have 1-2 Skirsdag High Priest in there because those demons are absolutely nasty.
I think I'd like to keep the one of card:Ghoulcaller's Chant, but I will consider adding in the high priest
Restoration Angel is VERY good with Messenger and Disciple.
oops i mean i agree with aneternalskeptic. Nice deck BTW +1
I will definitely playtest with those suggested cards. I really appreciate the suggestions, thanks!
Bloodthrone Vampire would give you a free sacrificing engine to trigger Blood Artist or to get instant counters on your Butcher Ghoul or card:Geralf's Messenger (who you could blink back in with no counters then re-sac when needed with Restoration Angel). Just an idea though, not sure what's worth cutting for it.
I thought about adding that card. I think Mortarpod to be the most effective sac engine for this deck (works great with Vault of the Archangel ). I'll have to consider adding a card like Bloodthrone Vampire once Mortarpod cycles out.
