UW Enchantments!

[Shax]

4 Serra's Sanctum
4 Flooded Strand
4 Tundra
2 Plains
4 Detention Sphere
4 Attunement
4 Replenish
4 Brainstorm
4 Ponder
4 Force of Will
4 Spirit of the Labyrinth
4 Preordain
4 Flusterstorm
4 Myth Realized
4 Merchant Scroll
2 Starfield of Nyx
SB: 4 Energy Flux
SB: 4 Swords to Plowshares
SB: 4 Rest in Peace
SB: 1 Energy Field
SB: 2 Stony Silence

So the idea is to put your enchantments away with Attunement, then Replenish or Starfied of Nyx them back to the battlefield to wreck opponents. I suppose you could go a more controlish route with Moat, Land Tax and the like.

Obviously good ways to stop your opponent are using Detention Spheres while beating down with Myth Realized or Spirit of the Labryrinth's to stop pesky Brainstorm draws or anything else they might want to use to draw. Starfield of Nyx eventually becomes a win condition and is what inspired me to make this list. I really want to keep the list based around getting Starfield of Nyx to turn everything into a creature as a lategame enchantment win con.

The sideboard contains just basic outs to whatever your opponent is on, whether that be artifacts, dredge, creatures, combo(stony silence to stop LED), or Energy Field as a catch all.

Spirit of the Labyrinth in your Brainstorm/Ponder/Preordain/Attunement deck seems suspect. What's it for?

you could throw in the opalescence + parallax wave wombo combo! you should look up how it works first, but basically with them both in play you can permanently exile all of their creatures, and probably have a team of 4/4 beaters (thanks to opalescence). attunement and replenish are both good helpers for this strategy, but you will probably need some other (cheap) ways to find and assemble your opal + wave combo if thats the way you want to go. maybe there is some way of fueling the graveyard especially well you could find in those colors.

you should probably take out your spirit of the labyrinth because it conflicts with your other spells (which are probably better).

Merchant Scroll is pretty mediocre. And you have no accelleration. How about replacing Merchant Scrolls with Grim Monoliths?
