4-Color Cards

Awhile back, a group of smiths and I were making a set based on all the 4 color combos. I'm trying to revive it and would like to see what else the community has in mind!
1. The card must include 4 colors
2. They should follow the ideas of the original set we made on Thefourmanaset page
3. While I'd like to see the keywords I used on a recent cycle of cards be used, feel free to come up with your own as well
Here's a cycle of cards I made for reference:
Spriannii: nonblack, based on enchantments- http://mtgcardsmith.com/view/spriannii-faith-mender?list=user#.VUUGN5NUWp0
Xchotar: nonwhite, based on graveyard meddling- http://mtgcardsmith.com/view/xchotar-lich?list=user#.VUUGlZNUWp0
Icari: nongreen, based on instants/sorceries- http://mtgcardsmith.com/view/icari-brainstormer?list=user#.VUUGrpNUWp0 (if you use this keyword, come up with another name for it since channel is already an ability)
Hiems: nonred, based on control- http://mtgcardsmith.com/view/hiems-frostcaster?list=user#.VUUG55NUWp0
Azteri: nonblue, based on token spawining- http://mtgcardsmith.com/view/azteri-berzerk?list=user#.VUUG_JNUWp0
And as 1 last reference, here's the old set page: http://mtgcardsmith.com/user/Thefourmanaset#.VUUHRJNUWp0
Good luck and good flavor!
