I was thinking of a few multicolors, to define their personalities better. For example, Eternion is obviously black (duh!, too), but since he´s the eternal of war and VERY aggresive and those things, maybe Black/Red would fit better. Anyway, we agree for the most part, even though there are a few ones I´m not so sure. Not every thief should be black. Black is the color of selfishness, search for power, and "the end justifies the means". I agree it doesn´t mean it is necessarily evil. It just means it doesn´t care for anyone else as long as he gets what he wants. Although it seems fit for a ninja to be black, I don´t think Karashi plays this role. And seeing his impulsiveness, easy-to-depress-ness (sorry, don´t know a word for this) and unreliability, Rio is more Red than Black to me.
In other topic, since I play green, am I REALLY stuck with Chookie? I mean, yes, I got Karn, but I´ve already sworn to play with ALL the members of the party that would fit my deck... and then, I get Chookie. Damn. Didn´t think of that.(Note to self: don´t make promises so quickly

.)
Well, to try this multicolor idea, I guess I´ll leave Karn and Ardam aside for a while, and do Eternion next. Let´s see where I can find a nice picture of Eternion that would fit a Magic card...
