Scute Outcast

I got the idea for the deck while I was looking for cards for another deck. Basically it tries to put as many lands in the game early on to make Scute mob grow and Dragonmaster outcast to start pumping tokens. It is an OK casual deck and I'm looking for some info and ideas to improve it. I thought about removing Zektar Shrine Expedition and reduce the number of Harrow, but I don't know what to put instead of them. Any ideas would be appreciated.
