Personally I would cut Amulet, joiner, gearhulk, and diabolic tutor's for more oath of nissa and oath of gideon and maybe just make it a green white blue deck and rely on your BoP, Oath, and call of the gatewatch to get you there. also maybe beef up your board wipes.

OOMJasonDavis with Amulet of Vigor it helps make it so that the dual lands I have in this deck come out and are available to be used immediately. Joiner Adept is there to help mana fixing so I don't have to worry about what lands I need out. Diabolic Tutor is there because I can only afford to run one Doubling Season and I want to make sure I can get it out as frequently as possible. And the Cataclysmic Gearhulk is there for a mini board wipe. However, due to this deck being in its begging stages some of those cards may go out. What board wipes would you recommend? Thank you for your comment!
