The point of the deck is to use Intuition to nab 3 copies of IGG. Two hit the graveyard. You ramp your mana up via Rituals, play IGG, sac Lion's Eye Diamond and get 3 cards back, including the Rituals you played, Lion's Eye Diamond and another IGG. Repeat until you're to your last IGG, and grab Intuition instead of IGG. Play Intuition for Tendrils. At this point, your storm should be passed 10.
Crypt is there to knock out Control, other IGGy Pop, Dredge and Threshold, possibly even Landstill's Wasteland/Crucible annoyance combo.
