I'm experimented a little bit with Psychatog in Peasant Magic. It isn't my specialty, but I'm pretty sure that the best Uncommon split for this deck is 3 Fact or Fiction, 2 Psychatog. It may also be reasonable to do 1 Psychatog, 2 Fact or Fiction, 2 Demonic Tutor. It's a difficult call to make. The more Fact or Fiction you have, the more you want to have multiple Psychatogs. With just one copy of Psychatog, if you cast Fact or Fiction and the top five cards are Psychatog and some combination of Gush, Brainstorm, Shadow Rift, etc. your opponent can put you in a tight spot by splitting the cards 4/1 with Psychatog in the small pile. Running a second copy of 'Tog means that you can comfortably take the four card drawers. Using the scheme with Demonic Tutor means that you can always look for whatever it is you don't have yet: typically Fact or Fiction, Psychatog, or Shadow Rift.
