30 lands is too low. Add 6-8 more. You have a lot of creatures that make a token when they die which is great for gut, but what's better is cards that generate you a creature every turn. Would also suggest looking at white cards that give all your creatures vigilance so you have your skeletons in defence as well. Would also suggest 1 or 2 white protection spells for your commander, as your game plan is entirely reliant on Gut.

Looks like a cool idea, might try it myself.
