Black Vise is an old artifact first printed in Alpha that lets you choose an opponent, and during their upkeep they'll take X damage where X is the number of cards in their hand minus 4
One thing I want to make clear: EDHREC is not a useful stat this first week, its more about enthusiasm than anything else but the cards arent always added in time

Feral Ghoul, meanwhile, gets stronger when other creatures you control die, and gives out rad counters to opponents when it goes to the grave
Bad Moon is subpar because you don't have enough black creatures and the majority of token creatures are not black, they're white or green especially since Prava only creates white creatures
