The "pox ball" is a monster, and can make for a seriously dangerous deck for 1 on 1 or chaos, the trick is to offset its recklessly destructive tendencies, artifact mana sources, especially the kind that doubles as a creature i.e. phyrexian totem, guardian idol ect. and straight up fixers like moxes(if youve been playing for a while or have one hell of a bank roll) sol rings, charcoal diamonds, coldsteel hearts ect. and plenty of mass destruction back up, namely the cards that spawned the idea for this abomination, pox and small pox, and some other good chaos bombs like innocent blood, mutilate, damnation, chainers edict, barter in blood, oblivion stone, curse of the cabal, ect. creatures that wont stay dead or help further complicate things for your opponent, myr servitor, nether spirit, undying beast/gravebane zombie, greater harvester, desecration elemental, eater of days, ect. and if ya pack a couple of feldons canes you can hang in there for the long haul as well as recover from overextending. All ya have to do is play out lands and mana fixers till ya have enough to turn on the gas and cripple every body at the table and activate the phyrexian totem for 5 to the dome against the helpless souls, and bust out the occasional consume spirit/Drain life to gain the life advantage and spread even more harm around the table(or to your 1 on 1 adversary) This card is definitely no joke in a mono-black build...Oh yeah, dont forget the dark rituals, they can do amazing things with those X cost spells.
