Y/b crystal rush!!!

I have been playing this as a rush deck and i threw in the shifting tides because it could be used for help with land placement if someone blocks you out of range i could see that being taken out in exchange for something else but it is also a low cost event to offset the windstorm colossus cost to finish off opponents and it forces another land for the crystal flower which is a temporary solution but it can be hard for opponents to deal with regardless. crystal flower takes the place of last nightmare simply due to faeria cost. it may not be the best deck in the world but it is working for me in the lower teirs
