I feel like some of the creatures are kind of odd. AEther Adept and Perilous Myr don't really fit an Esper control deck in my mind.

Consecrated Sphinx and Wurmcoil Engine are good considerations; I'd run either over Frost Titan .

I like AEther Adept because if the timing is right you can really set an opponent back an entire turn. It also works great with Venser or resetting a Fiend Hunter or Evil Twin if need be. I was looking for cheap chumper in Perilous Myr . I like that it both blocks and potentially take something else down with it. Maybe there's a better choice for that slot.

I think Solemn Simulacrum might do better than Perilous Myr .

You might also want to look at getting another Venser, the Sojourner or two if you want to abuse his ability.

I would be dropping Perilous Myr and Frost Titan s Consecrated Sphinx is just to good to look over for a frostie, and Perilous just is not that good all in all if you want something good for venser to exile put in Solemn Simulacrum land ramp mini combo.

you also have to many creatures, keep the creature base around 8 or 9 anything over 10 is just to bulky, I think anyway. so all in all drop Perilous Myr Frost Titan , make Doomed Traveler a 3 of throw in some Snapcaster Mage another AMAZING combo with venser nad like Epochalyptik said add some more Venser, the Sojourner

that's just my 2cents if you like the advice GREAT if not oh well

The creatures are the best of these colors that I have available at the moment. If I owned a wurmcoil, sphinx, or sun titan I would work those in as well.
