Like the cards but Gray is busta already!
I used to think so too, but it's far from the ultra-dominant force it used to be from what I've seen. I wanted three brigades to make both one per deck, and gray seemed to fit in both cases.
why not flip a coin if you just need 50/50 odds?
Ha, that's true. It used to have three effects (one for 1-2, one for 3-4, one for 5-6) so I used a dice. But I didn't really think much on it when I shortened the ability so the dice stayed. Also, you're less likely to lose a die than a coin.
