At 38 lands, I think you could get away with cutting one to run The Gitrog Monster .

I'm not sure why you have Batterskull here...I get that its a great equipment card, and beating face is fun like that, but it seems to me that you want to be getting value from Glissa. Cards like Viridian Longbow , Pathway Arrows , and Thornbite Staff provide you with instant value from Glissa.

I notice you are very tutor-heavy, as well. You might consider dropping one or two to make room for other cards you want to run.

I was curious, how well does Masticore work for you? Do you find you have trouble keeping it around with the upkeep cost? I do see how well it can work if you have a way to give it deathtouch.
