I don't think this really needs the green. Just keep it U/W.

This. If you want ramp I'd suggest just using {sphere of the suns}

[Bloodguilt]

As u/w this deck is fun but if you want to keep the ramp I suggest maybe using {sunpetal grove} and/or {razorverge thicket} just to have a garuantee on having green mana for your green creatures. If you drop the green {seachrome coast}. I really don't know much about control but I've been running an r/u shape anew and noticed having double lands of my most common mana and least common helped a lot.

Well, no green now.

Added cloud shift for flicker snap and stonehorn
