I know Sram, Senior Edificer doesn't have hexproof, but he is a unit for draw. Commune with the Gods is a little too slow for me, switch it out with sram? also maybe Gods Willing against sweepers, or in maindeck to prevent blocks. Also maybe Gideon's Intervention in the sideboard against dimir inverter. Looks like a cheap good deck. And I think Sunpetal Grove is better, although not strictly better. You could play 6 copies between the two of them, or else you will have some slow problem hands when you dont have any basics or shocks.

The best way to protect against sweepers is Karametra's Blessing. Sometimes it also helps get in that last little bit of damage.
