Mono Blue Pauper deck using Peregrine Drake, Mnemonic Wall, and Ghostly Flicker to go infinite, with mill as a win condition via Jace's Erasure and card draw by flickering Mulldrifter.
Edit: Swapped out Whirlpool Rider and Remote Isle. Found I was already getting enough card draw from Brainstorm and flickering Mulldrifter, and I really need to get to 5 mana, but once I do, extra lands are garbage cards. Replaced with Counterspell and Gigadrowse to help me live the first 4 turns.
Edit2: Put it back in for Gush.. makes much more sense I think. Helps cycle when I'm hunting for Ghostly flicker with Mnemonic Wall and Peregrine Drake already on board, and used for win condition.. Gush kept putting me too far behind when I took back lands, and paying 5 to draw 2? I draw more with Whirlpool Rider in most cases.
Edit3: Took it back out. Replaced Ponder/Brainstorm with Compulsive Research, Preordain, Serum Visions to better dig through the top of my deck looking for combo. Went down to 3 Erasures because I dig them all pretty quick after going infinite, and only need 2-3 to win. Also removed cycle lands.
Edit4: More tweaks. Optimized Sideboard. Think it's ready for Pauper this week :D
