Haven't found old Saint Traft yet, but here's my new build... It just feels slow. Like, I'm dead before I can really do anything. Maybe I need less spirits and more spells?
I felt compelled to post because it's very similar to yours. Essentially, it's a combo deck. Drogskol, then phantasmal image. Beat with big flying dudes. Geist with a sword, token gets buffed by Drogskols and the enchantment. It works pretty well.
Only thing is board wipes, and Ratchet Bomb . Those things screw you over hard. And if you don't combo, well...
I wanted to run Delver in there somewhere as well, but I don't feel I run enough instants or sorceries. So Doomed Traveler it was =P
You also definitely need Oblivion Ring . I run 2, but have an additional 2 in my sideboard. You need them for planeswalkers.
