Depending on how big you want your defense depends on what type of black you want to run. Black was the strongest small and large brigade last year, IMO, so obviously, it gives you lots of options. Phillies are great for a small defense. With just Philistine Outpost, Philistine Armor Bearer, 12 Fingered Giant, Goliath, and Philistine Garrison, you have a powerhouse defense for early game, and really good against banding offenses. You can also throw in negates for support, such as Bringing Fear, Foolish Advice, Devourer, and Joseph in Prison. Simon the Magician can fit well into these decks if you have more than just negates, and he's also a magician that you can use Magic Charms on. Greeks are surprisingly good, especially if you mix Black and Orange. Antiochus Epiphanes, Winged Leopard, Goat with Horn, can all be great.
