This isn't even the card I nominally endorsed in the discussion we had in #themanadrain.
One, Ball Lightning plus ACC
must have a higher mana cost than Ball Lightning.
Two, as I stated after we'd hammered something out that I was okay with, I realized it isn't the bringing-into-play that makes Ball Lightning red. It's the fact that it's a creature that behaves as a burn spell. Because this, like Red Ball Lightning, behaves like a burn spell, it feels red. If you want me to repeat some of my suggestions for ways to make this feel more black, I'd be glad to.
