I'm thinking through whether brainstorm as the only blue card (that you're generally casting, at least) is really worth the concessions in the manabase, and I'm concluding that yes, it is, since there are numerous cards you really never want in your hand and want to get back in your library if possible (Progenitus being the most egregious).  Nothing seems amiss in the maindeck without more testing.  I could see a case for Mogg Fanatic being something like Death Cultist to get around fringe things like Glacial Chasm, but I wish there was a 1cc creature that did that AND got around Leyline of Sanctity / Solitary Confinement; I'm not finding one.  I initially liked the idea of sticking Pattern of Rebirth on a Hope of Ghirapur, but it's not GSZ-able and you have to resolve the Pattern before you get its ability, so maybe not worth it over Xantid Swarm.  As for the sideboard - seems like overkill on the removal to me, and not enough diversity of other stuff.  I could see cutting to 1 Pridemage, since it's mostly a GSZ target anyways.  Beast Within is cute as a way to kill Rector when it's your only creature and still have the 3/3 body to put Pattern of Rebirth on.  But with Rector as a 1-of, and a pretty high creature density in the deck, that seems sort of fringe, and otherwise I feel like Pridgemage + Abrupt Decay takes care of most of the permanent hate we're worried about.  The gravehate seems light - I could imagine a couple Surgicals in the board depending on how the meta shifts.  The Sneak and Show matchup looks... strange... since if you have an instant speed sac outlet in play and a Protean Hulk in hand you can kill them at instant speed after they cast Show and Tell.  If that matchup is a problem (seems like it could be since they are fast and can disrupt us), what about running a couple Summoner's Pact in the board to make getting Hulk in hand more consisent?  Also, what about a 1-of Gaddock Teeg to GSZ for?  Can always sac the Teeg when the time comes to cast Pattern / NO and kill them.
