MTG Salvation

I accidentally built a casual four color, non-white, deck around warp world that feels very non-white. This inspired me to make four more decks, one each for each other color to exclude, that feels very opposite that color. Unfortunately this is far too open ended a challenge and it's overwhelming. Any ideas for build around cards/non-infinite combos that would help exemplify the exclusion of a color? Or just really wacky, warp world level of splashy, build around cards in general.
