Man, let me tell ya, this was a toughie. I'm still not happy with taking Cuombajj Witches ability here, since my first thought is "I don't want this to deal 1 damage or grant -1/-1. I want to see these two colors do something different." But black/red's shared skill set is roughly "burning and destroying things". Outside of that, this would need to be a card that ideally gets played on round 1 (it would be kind of silly if this granted haste, eh?), and likes to play defense. Alternatively, I did think of using Suppress, except the player got to keep one card... but figured that might be too much to convey on a common (It would also be a stretch convincing people that was red. New abilities get some leniency, but it wasn't really in red's skill set to tell people to hold back...). Heck, this is probably too much to convey on a common nowadays. I'm still not thrilled.
