Yeah we are talking about the same thing. I didn't play the monoblack since a long time, it still looks more consistent than bg (due to all reasons we already said), but it still hits those walls you said.
There is an inherent attribute to Black that is: you CAN drw cards, but this has a cost in life. But, with this heavy disruption, do we care about life loss? And adding effects like phyrexian arena (or whatever draw card you remember of) won't dillute the strategy? (since it looks like all the cards are essential)
