Selesnya elves might be better with Mentor of the Meek, Selesnya Evangel and Reprisal. Also God's Willing for protecting those important creatures, like Timberwatch Elf.
Mono Green elves could run Scion of the Wild, maybe even Chorus of Might.
Unfortunately; as I was worried about above, it's seeming like the white splash may have to happen. I was doing my best to stay away from Selesnya since it's one of the most common/popular color combinations in DotP 2015. Having said that, my few test runs with Mentor and Evangel were strong. I had dropped Primal Bellows for Sigil Blessing which was fine but I'm on the fence about Gods Willing. It's a top tier card in this format and it may eventually be worth using it to save creatures/ push through damage but at this point, I'd rather just keep powering through the deck with draw and dumping more to the board. If I could find a way to draw more consistently, than I wouldn't worry about it. More testing and time will tell.
Timberwatch Elf could make Reprisal playable.
I hadn't considered that but it could be interesting removal. There should be more than enough elves in play to make it consistent. So far though, removal hasn't been the issue. I can usually get my whole hand on to the table in just a few turns and can generally pump wide on swings which makes removal less of a requirement.
Slow playing a deck like this isn't very advantageous especially since it gains strength from it's numbers. So it's more about how I keep up with the deck's pace of play and restock my hand and board state. I'm just concerned we don't have the options in our card pool.
