Making Magic: The Council of Colors, Revisited

I know about the Great Designer Challenge question, and I agree that while such a creature would technically fit into those 2 colors, it's not doing a thing that those 2 colors specifically want to do together.

The value of a flyer is to get in around something, and the value of vigilance is to be able to attack and still safely block. Golgari's approach to those goals is usually good removal in black and big creatures (with trample) in green.

Beyond that, you'd have to consider the rate of the creature. 2 mana 2/2 w/ flying and vigilance? Banger in Azorius, but doesn't do jack squat for Golgari. If you go over rate (because green and black both have a number of creatures that are over rate) and get a 2 mana 3/3 w/ flying and vigilance, is that just broken? Even if it's great, does it see play?

Strictly mechanically, it's pie-compliant. Just because no card like that was printed prior to that Great Designer Search quiz doesn't mean it's a break. As a comparison, flying trample is typically mono-black, but there's no issue with those two abilities on a blue-green creature; blue provides the flying and trample provides the green.

Oh, hey.
