how do cantrip strategies win? Favorite win con in each color?

I see decks like Feather and Zada and Kykar run a lot of cantrips... but, then, I was thinking how do they win?? I think it would be fun to do a 5-color deck, but it doesn't feel very effective. Sure, there's a lot of protection spells, but otherwise... what do you do? How do you win?

Green has some cool cantrips that I feel can be abused. White could be good for protection. Red has lots of options. But, again... all of the above are low-impact. So, what's the path to victory? Mizzix's Mastery and hoping your opponents don't have graveyard hate? Yet another storm build? Is there a fun and unique way to pull out a win? If so, give me your favorite in each color?
