With much inspiration from Travis Woo, I present you: OmninfiniteThe main win condition is to ramp up, casting an Omniscience, then cast Enter the Infinite, Laboratory Maniac and Temporal Mastery for free. The next turn, you cast a Sphinx's Revelation. Boom.
Another lovely win condition is to ramp up and attack with a huge Griselbrand thanks to Kessig Wolf Run.
I've sideboarded against Aggro mainly. This combo is just too slow to keep up with very aggressive decks.
Thoughts? I really want to try this deck at my LGS sometime.
I've been goldfishing this all night. Normally I don't care for flat-out combo decks, but this seems really fun.
Have you considered Think Twice? It would allow for some easy draw while getting your engine online and could allow you to win outright when you cast Enter the Infinite instead of having to use Temporal Mastery and Revelation.
I would personally run some more Dispel and Terminus in the sideboard, but that's just me.
