Hedron Alignment Deck (SOI Standard) (Standard)

By using the combo of Starfield of Nyx and 2 or more Oath of Jace you will be able to draw 4 cards and putting two in your yard. This can be repeated every turn because of the legendary rule so as one comes in to play the other will go to the yard and then next turn repeat that by replaying the Oath of Jace with Starfield of Nyx (you can do the same thing with all oath cards). The rest of the cards are to stop all creatures that come it to play that you don't want there till you get your Starfield of Nyx to start beating on your opponent with your 5+ enchantment creatures. This is the main way the deck wins.

When playing the deck the most important card to keep around is Starfield of Nyx so save counter spells to protect that.

A lot of the time your game will go on for a long time so you need as much life as possible, don't be afraid to block with your Stasis Snare and Silkwrap because you will more than likely be able to replay it in your upkeep (with Starfield of Nyx) and it will be as if your opponent just wasted their attack.

If you have a Planar Outburst without a Starfield of Nyx feel free to wipe the board it won't effect you. But if you do have Starfield of Nyx out and your enchantments are creatures there are a few things you can do so it won't damage you to much. during your opponents turn use Eerie Interlude so anything you have exiled with Stasis Snare and Silkwrap will be back on the board ready to be wiped and all your enchantments will be safe in exile. You don't even need to exile all of them just enough so you have four or less.
Your second option is that you can just full out attack and hope your opponent blocks/destroys enough so you have four or less.
Finally you can just use Planar Outburst if you have the single Starfield of Nyx because in a turn or two you will be able to recover by replaying your enchantments from your grave with Starfield of Nyx.

If you have nothing in your hand remember you can scry with Hedron Alignment and put counters on Myth Realized.

Also when playing Pacifism from your grave with Starfield of Nyx you are able to get around hexproof. "if an Aura is returned to the battlefield this way, whatever the Aura enchants isn't a target of Starfield of Nyx's ability, nor is it a target of the Aura card itself. You could put an Aura onto the battlefield this way enchanting a creature with hexproof controlled by an opponent, for example." (This was copy and pasted from http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=398475 )

The main reason Eerie Interlude is in the deck is to protect Starfield of Nyx when I have two out and say someone casts a creature only board wipe you can exile your Starfield of Nyx so your enchantments aren't creature or exile enough so you have four or less. It also works well with Planar Outburst, so if you exile your creatures during your opponents end step so when you use Planar Outburst it won't destroy any of your creatures.
The other benefit when they or you cast a board wipe you can exile your Stasis Snare and Silkwrap putting what ever you exiled with them in the first place back on to the field ready to be wiped away and then at the end step you get Stasis Snare and Silkwrap back.

If you are in a slow game or you have a control match up try and pull off Hedron Alignment.
You will be able to get a Hedron Alignment in your yard by discarding it from your Oath of Jace. If you are finding it hard to get it in the yard you can just keep attacking with it till they have to block it.
To get Hedron Alignment in exile you will be using Fate Forgotten or Eerie Interlude (you use Eerie Interlude at the end of your opponent if you are using it for Hedron Alignment).
Once you have played two Hedron Alignment on the field and discarded the third keep the next one you draw in your hand. So at that point when you draw a Fate Forgotten or Eerie Interlude you should be all set to win.
