I can see the idea of the thread, and these are my opinions :
4 Divert ? Why ? To save your Morphlings ? 4 Misdirection is already overdoing it I think, 2 or 3 are more then enough.
Treachery? This thing costs 5 mana, this won't save you from ritual-negator if you happen to just miss that fow in your first 7 or 6 cards. I think you couldn't pay me to play this card in mono-blue.
I think you are somewhat land-light. only 17 islands + 4 strip effects, is a low margin on land. Generally, control decks like this tend to run more.
Do you really need 4 Morphlings? I think that's overdoing it, 2 is more then enough.
Cards I might be missing from the maindeck:
-Cunning Wish - get your sb-solutions game 1, usefull for fetching of your 3rd or 4th misdirection, a CapSize, a counterspell, a Blue Elemental Blast, stuff like that. It's great, and I would recommend 2.
-Back to Basics - this depends higly on your metagame, but you want to do something against all the decks trying to abuse the basic lands.
-Manlands - An extremely solid way to bring some beats to your opponent if you choose not to run Back To Basics. I might be old fashioned about this one, but a few Mishra's or Conclaves never hurt anyone
- Except your opponent
oh, Also, I don't think Lotus Petal is worth it, but that's up to you.
Maybe turning it more into Ophidian.dec would be nice, there's also a few nice threads on it in the vintage forums.
