Also, in addition, I've never really been happy with Sword of Body and Mind; so I'm planning on running 2 Feast and Famine and not running the other at all.
It does serve a few purposes but I just can't see myself ever playing it anyways. If you don't have any action they can just bounce it and kill you anyways
I'm pretty sure Leyline is disadvantageous (bad) most of the time. There are better ways of handling Fae. If you have to mull into Leyline you're already losing.
Edit: Interestingly enough, the UW list which won the last MODO PTQ (http://www.wizards.com/Magic/Digital/MagicOnlineTourn.aspx?x=mtg/digital/magiconline/tourn/1976688) beating RDW in the finals ran 3 copies of JTMS. As bad as he is in that matchup I can't see having less than 2. No Leylines
Yeah basically, otherwise you're pressed to have UUU, RR, and WW while still packing Tec Edges and Colonnade.
Edit: I've been pondering MD Spell Pierce instead of a red splash. Pierce is just about all I can think of that would help without adding colors.
Equilibrium!
My list was also pretty similar to yours.
