No Xenagos, the Reveler? Over Prognostic Sphinx maybe?

If your going for a superfriends deck you should really have black for Ashiok, Nightmare Weaver, she just gets you things to use or simply gets them out of the way. Liliana Vess, its a tutor for ANYTHING! Garruk, Apex Predator can defend himself with deathtouch creatures or wreck a control deck that just played a planeswalker win-con. Also, lifegain is useful. Just drop a land or 2 for Urborg, Tomb of Yawgmoth and you should be alright

When Narset Transcendent comes out that would be a great thing to add. If you haven't looked at her here's a link.

Thanks guys for the feedback, main reason I don't have any of them in the deck is cause I don't have them (I was just typing up the deck as I had it). I've updated the deck with the suggestions, (and now I've got some cards to get now) and thinking about replacing the Banishing Banishing Lights with Hero's Downfalls, but I think (for now) it might be a bit too hard to get the double black early if I don't get an Urborg, Tomb of Yawgmoth.

Narset, Enlightened Master goes great in these decks. Especially in combination with Prognostic Sphinx.

This is the definition of super friends. You have my +1. What would you put in place of Narset Transcendent if you don't have one?
