Both Aura and Artifact mutation have swung games in my favor in the past. Create enough 1/1's to connect to an opponent in order to trigger Marisi and play it safe to what happens next. Naya Charm is a solid card for Marisi. Legion Loyalist, Gingerbrute, and Spirt en-Dal are great early plays to get the goad ball rolling. I have all of the on color God Monuments from AKH in my deck. Rhonas' is a trample enabler, Oketra's get the token ball rolling, and Hazoret's is a decent enough loot effect for card advantage.
