adding omega agent is a good option. Especially if you lack Mojomaster it´s a solid replacement. the first matches showed great gameplay and synergies. the deck would like 1-2 healing options more but not shure which card would make it ... I edited the deck and will try that version.
broodmother might be useful. The witchwood imp actually worked well but not enough games till now.
I like it very much. :-). Great board play. It´s cauldron fun delux.
Edit: contiued to play great. Not shure how to tweak it to be eve nbetter. Coul use weapon removal, Raffam or again Broodmother. Zihi is great but actually not very impactful due to alot of aggro decks. Glinda is basically a must remove so a good soft taunt.
