I'll probably cut Sphinx from my list. I boarded it out 100% of the time, even when I kept DR Zealot in. In the past it's given me more turn 1 wins in game 1, but you have a good point we probably win those game 1s either way. Don't need to discard their whole hand and attack with 12 3/3s on turn 1.
I'll stick with Zealot over Kolaghan for now. Zealot's haste sticks even if the Zealot dies (you can even sac Zealot to Therapy them pre-combat and have back-up zombies to block if the attack fails). 3/3s are better than 2/2s, and that difference has won me games when there were a number of chump blockers to beat through.
I would play Ashen Ghoul over Shadow too. 1/1s suck. Manaless plays Nether Shadow only because they can't play Ashen Ghoul.
In my post-board games where Ichorids got extracted AND Bridges got exiled, Narcomoeba and Golgari Thug and Stinkweed Imp beatdown really wasn't getting me there. I don't think another 1/1 would have helped. 1/1s are too slow and too easily stopped.
