I've started testing this deck again as well. It's been doing alright, but I've got a lot more testing to do. Notable matches so far are RG Combo-lands and a fair share of four color control.

Things that my testing has shown me:
When I actually draw into my
Soothsaying, I'll tell you how it plays. Theoretically, early game it's a mana sink for a less effective Sensei's Divining Top, and late game it's essentially a
Vampiric Tutor that doesn't shuffle when it's done. Is it worth the space? Once again, to be determined.
Stifle was initially
Trickbind, but since I was essentially sniping fetchlands most of the time, I decided to risk the one drop one for the time being. If Griselbrand or Split Second become more relevant, I'll switch back.
With
Deathrite Shaman being praised as the best creature in the format right now,
Pithing Needle is good. Good beyond halting
Wasteland.
One thing I may try since I encountered a lot of low curves is siding
Chalice of the Void (then again, that's also from the fact I'm coming back from playing MUD-Post and Legends of Colorless/Big Eldrazi for the past year), and Trinket Mage helps them out.
More testing to come, but I will say that I feel the demise of the Classic control of "12-Post" has been greatly exaggerated.
