Stonybrook Schooling is a heavy U/W lockdown deck that can stall or win a game on its own merits, doubly so if it reaches a combo condition.
It can lock out combos with Meddling Mage (or Boomerang threats and then Meddling Mage them before they hit the battlefield again), tap-lock important creatures/artifacts/lands with
Aphetto Grifter
, counter everything with Patron Wizard (and it's 34 wizard creatures), and gain life for all of this tapping via Judge of Currents.

helps make sure I get the draws I need, while Vedalken AEthermage is an extra wizard in a pinch or a wizardcycling card if a key part of a combo is absolutely needed to lock out a certain deck.
Once
Stonybrook Schoolmaster
hits, things begin to get crazy. Every time it taps for Patron Wizard or Aphetto Grifter it gets me an extra source of healing, countering, or tapping. With two of them on the field I can eventually generate enough wizards to basically perma-lock my opponent from having mana, creatures, or spells at my leisure. The tokens also make great sacrifice fodder for Voidmage Prodigy.
My win conditions should be fairly obvious: perma board lock via Patron Wizard and/or Aphetto Grifter plus sufficient wizards, deck removal via Supreme Inquisitor and sufficient wizards (done at the end of my opponents turn to allow for tapping/counterspelling if needed), or an infinite creature combo courtesy of Intruder Alarm and Stonybrook Schoolmaster.
Sideboard needs help (no real ideas on a good sideboard), and the Maybeboard is still in consideration, obviously. Thoughts are appreciated.
