i have played esper control since RTR started and here is my 2 cents:

memory adept and liliana should not be in here. elsepth and architect of thought are much better.

if aetherling is your win con, he should probably be the only creature since you should be supreme verdicting a lot

speaking of supreme verdict, you should have 4. and 4 detention sphere

Hero's Downfall should also be at least a two of.

dimir charm is not that good either

Dissolve seems like it would be good. more far and away.

Heliod, God of the Sun might not be bad either. good mana dump

When i built this deck Theros wasn't out yet. Hero's Downfall will probably replace Doom Blade . Dimir Charm has helped me out a lot around where i play. Combine it with Azorius Charm and its a second part of an answer to a lot of things. Far / Away helps with indestructable/ hexproof creatures. Heliod, God of the Sun wouldn't do much but sit there as a 4 drop enchantment. Also AEtherling , Obzedat, Ghost Council and Blood Baron of Vizkopa have all won games for me. I might add Dissolve and take out Negate or Essence Scatter . I will also probably end up putting in a few of the scry lands.

Not sure what i would take out for another Supreme Verdict and Detention Sphere though
