good deck

So first off, I don't know anyone who is outright going to build a deck for you.  The whole idea of this portion of the site is to look for comments on existing decks or get pointers on how to improve your general deckbuilding practice.

That being said, I took a brief look at your inventory and you certainly have the fetches and some of the bigger value cards to look at building Esper (blue-white-black) or at least Azorius given the Flooded Strands and Elspeth, Sun's Champions you already have.  Personally, unless you're super attached to the foil strand, you can trade it for 95% of the remaining cards you would want.  I would recommend building a more controlling build that centers around Elspeth and Ugin, the Spirit Dragon as your primary win conditions.  This means you'll need plenty of removal and counters... think End Hostilities, Banishing Light, Dissolve, Dissipate, and things of that nature.  Other cards to consider including are Aetherspouts, Whelming Wave, Suspension Field, Dig Through Time, etc.

Beyond that, once you have a build pieced together I'd imagine you'll get much more input.
