Have you thought of replasing Boon Reflection with Noble Purpose? It probably helps better with Cradle plus you get an open slot in Lifelink

Not enough counter but pretty good burn. I'd suggest removing 2 chalices and adding some counterspells and/or boomerangs. You could also swap or sidedeck Earthquake with Starstorm, if you can get your hands on it. It is slightly more expencive than quake but it damages flyers as well, plus it has cycling. Otherwise pretty solid deck and kudos to you in using Deprive to bounce the effects of Peaks and Depths :)
