No {Shorecrasher Elemental}?

I would reccommend replacing {triton shorestalker} with {shorecrasher elemental}.  It has too little impact on the game to be a relevant threat. Otherwise, the deck seems pretty good.

20 lands and 5 colorless can make it hard to hit.

well, you can always megamorph it, thus requiring only 1 blue source
