Best black pillowforts

Hi,

I m trying to build around [[The Witchking of Angmar]], hindering my enemies to attack me, while I get advantage from Monarch & Initiative effects.

What are in your opinion other effects I could utilize to my advantage while not being attacked? And are there other cards in black that disincentivice attacking me (apart from pillowforts like [[Hissing Miasma]])?
