This looks pretty legit to me. Most U/W decks I've looked at haven't been tested very well or are just janky in general. I'm diggin this build though. +1 from me.

Suggestion: Swords. You're mid range? Run swords haha.

Check out my latest deck? TurboFog post Avacyn

The Drogskol Captain seems a little limited only able to give other captains and your geist hexproof and the boost, but at the same time I hesitate having you pull it out because having a geist wiith hexproof is pretty freaking great, and another +1/+1 on it can't possibly hurt much. There's Elgaud Shieldmate which gives the hexproof but can be given to anything but that's at a more expensive cost and without the boost. Then there's Honor of the Pure which will help all of your stuff but will not provide hexproof and can be slowed down a bit by Thalia. Ajani, Caller of the Pride can put counters on your double strike guys or whatever you like and the -3 could be huge on a Champion of the Parish but really I'm just speculating to myself. What you have right now seems better than all those to me. . . Pretty solid man.

Also, Tamiyo, the Moon Sage and maybe try working in the venser-stonehorn lock.

Would you not run Cavern of Souls instead of the Islands? Perhaps 3-1.

If it's an issue with Geist, you can always name Cleric and then it unlocks for Fiend Hunter, Grand Abolisher and even Leonin Relic-Warder if you had them sideboarded.

I would if I had any, but money is tight so I can't spend to get them. I'll definitely keep an out for anyone with them in trade at my local tournaments
