This I my favoured Mono Black Control deck which I’ve won multiple FNm’s with.
Witch’ Cottage is awesome and the addition of Twisted Abomination can search out the cottage and then return the Abomination to either repeat or play as an additional threat.
The deck has multiple removal spells and creatures to allow for a very aggressive local meta.
