Esper Superfriends

[conley1000000]

So thinking back to standards past one of my favorite decks was Superfriends. Of course that involved Ajani V and the color red, but looking at the GP Toronto top 8 I saw an updated version of the deck, in the form of Esper.

I like the looks of the deck. I feel like the set up is strong. Played around a bit with the list and notice Affinity is a very tough matchup for it.

Also I'm not a big fan of Oust, the deck could need it but I'm not convinced it does, so I tweeked the deck a bit and came up with these changes:
-3 Oust
-1 Detention Sphere
-1 Gideon

+1 Path
+1 Sphinx's Revalation
+3 Mana Leak

That was my first testing. I like a bit of permission, but would Remand be better than Mana Leak in this style deck?
