@Satsuki:
I thought it was the opposite.
Nope, first person that said that got mixed up. The official-er sources say the eagle is in White and the vulture is Black.

White gets plant thing, green slime psychic thing, eagle, cover black legendary, and genie #1.
Black gets cloud thing, black gothy thing, vulture, cover white legendary, and genie#2.
And theres a couple critters that only evolve with trading that are in both.
Given that in every single case except the cover legnedary, I like the creature in white better, my choice is made easier than ever.
