I feel I played it safe, relying on multicolor synergy and solid aggressive creatures to see me through, with Scourglass as a backup plan. The time to play Cascade in this deck is precombat, with strong creatures on both sides of the board, preferably after the borderpost is safely out of your library. I occasionally bordered in Bant Battlemage to finish off Crystallized creatures. Vengeful Rebirth is even better than it looks, by the way.
