Here, have this Celestial Dawn.
It is the will of Zedruu.
I dig this deck. Zendruu is super fun. One thought, since Celestial Dawn is devastating to a non-white player, but not one who can produce white mana, maybe run something along the lines of Glamerdye , so you can make it work with all players (except 5 color, obviously). Make all their lands plains, but make red mana the color that can be spent as any.
That's a pretty cool suggestion, the only problem I got with it is that it will only benefit one card in my deck (and maybe chaotic backlash to a degree, but even then it's only two cards). I'm not a fan of having isolated combinations like that. Still, it could work since you can potentially screw with other peoples spells as well. I'll have to think about it.
