@brass-man thanks! I bit the bullet and got a manatraders subscription to try it out. Have to say I am definitely impressed! I took your list with:
-1 Elvish Spirit Guide
+1 Squee, Goblin Nabob
The squee was never really relevant in any of the matches, but went 4-1. On my first league ever! Lucky with the opponents I got: won 3x xerox, 1x BUG, and lost 2-1 to PO. That last one was in part due to my complete ignorance of the deck, and got the wrong cards using thoughtseize.
I was often lacking a mana or two, so will try with an additional fetch next time. I agree on the ouphes, they were essential in my match win against PO.
Very enjoyable format, I think I'll stick around for a little bit
