Ideas for Nekusar

So a few thoughts on Nekusar builds:
- Wheel of Fortune style effects are where it's at in a Nekusar deck.  You have a few, but think Whispering Madness, Reforge the Soul, Burning Inquiry, and Dark Deal to name a few.   
- Because of all the discarding going on, this is among the decks that could actually make quality use of Waste Not as well. 
- Given the amount of stuff that will be filling your yard, you might as well toss in any quality Delve stuff too.
- Also, added card draw is pretty big here.  You have Dictate of Kruphix, but you should also include others like Howling Mine, Font of Mythos, etc etc.
- Given all the wheel effects you also will likely want some mass Unsummon effects like Whelming Wave, Cyclonic Rift, Devastation Tide, and more.  It's good fun to get them to pick up all their stuff and then drop Whispering Madness to make them discard all those cards and draw another 20 cards, triggering Nekusar for each one.
- You probably want to drop most of the creatures you have as it would be best to adopt a more controlling strategy.  Think removal, card draw, and all those sorts of things. 
- Might as well toss Ugin, the Spirit Dragon in there too - mostly for grins more than anything else.

I'd also say to just Google "Nekusar EDH" and you'll probably come up with a TON of builds to draw ideas from.

I hope some of this helps and good luck!
