Collectible Card Game Headquarters

The sealed deck AI seems to have some problems with Hybrid Mana. For example, it would not put a Vassal Soul (1 W/U W/U) into a Black/White deck.

I think it's because CardColor.containsAllColorsFrom() treats the hybrid mana as requiring both colors to match. But that's not right for this purpose.

So that's as far as I got -- only enough to see the problem, but not enough to have any idea about how to fix it. Any suggestions?

Hmm, interesting.
I have made a similiar thing in r17412

Awesome, thanks!
