I have I think three 3-1s in MTGO dailies with Paradoxical Outcome decks sporting a rainbow land manabase (4 Spire of Industry, 2 Mana Confluence, 2 Glimmervoid, and Academy). Being able to pretty consistently play spells in all five colors is pretty awesome. Nevertheless, I've since preferred to return to the more traditional island-fetchland package. The shuffle effects make your Tops way better, and (along with tutors) allow you to run Brainstorm. But, more importantly, the mana base vs. Shops is way better, since you can keep a fetchland uncracked or just get basic Island.
This new card definitely changes the calculus. Still, my gut says relying on six mana to get this card to work is too sketchy too incentivize me to abandon the fetchland package again.
