Technically this is not about prohibition, but rather punishment. I don't much care if creatures die, creatures are cast, spells are cast, things go to the graveyard, things are discarded, or cards get drawn (by my opponent). I can realize a net benefit by any of it. I included my typical self-feeding burn-and-kill combo here as a side note, though either of the components can work well with other elements. There are only 17 creatures, which is very low for me, but with so many ways to manage things on the other side, I think I can fight well enough to win regularly. With a 13/19/4/2/2 curve, the average is a respectably low 2.03, though I retain both Sol Ring and a trio of Dark Rituals.
