I've been testing this list to good results:
4 Prog
4 Inkwell
4 Emp Archangel
3 SSS
3 UW Cascade
4 RG Cascade
4 Show & Tell
4 Force of Will
4 MisD
2 Hypergenesis
4 SSG
4 ESG
4 City of Brass
4 Gemstone Mine
4 Forbidden Orchard
4 Sulfur Vent
SB: 4 Intuition
SB: 4 Krosan Grip
SB: 4 Jund Charm
SB: 3 Platinum Angel
You'll note that I only play 7 cascade cards. Hypergenesis is a mixed blessing in that sometimes you have your worst guys (Emp Archangel or SSS) and your opp drops 2x goyf or goyf + some exalted dudes. Other times, you run into a real aggro deck and they drop a fistful of goblins, merfolk, or elves. In my mind, losing games where you resolve your best spell is unacceptable. S&T remedies this problem by only giving them one guy (who is unlikely to match even your worst dude (SSS)). S&T incidentally avoids problems with Chalice @ 0 (Intuition postboard helps you find it more often) and pitches to Force of Will better than Demonic Dread. It's also far easier to cast than Ardent Plea or Demonic Dread.
