Deck is nice. I mean, I don't have dead cards like normal UB Teachings:
Doom Blade,
Grasp of Darkness or
Victim of Night against Angler decks, but mana can be annoying here :)
For me - sometimes I have problem with wincons. I mean, I can't find them (have ~43-45 cards to find. If no - it's auto lose), and Forbidden Alchemy help me to die, so I need something other, but I have no idea... Peer Through Depths/Impulse, Petals of Insight/Foresee or maybe some tutors like Muddle the Mixture?
Ehh...
