Prophet of Kruphix + Arcanis the Omnipotent = draw and cast three cards during every player's turn at instant speed
Prophex of Kruphix + Cloudstone Curio = activate your enter-the-battlefield effects forever while maintaining the maximum possible hand size for Overbeing of Myth
Prophex of Kruphix + Cloudstone Curio = Flash your creatures into play in response to your opponent's removal spells and bounce their designated target
Nevermaker + Cloudstone Curio = stack the same land on top of your opponent's deck for the rest of the game, along with any other permanents on the field that you want buried on the top of their deck
Note: if you have multiple copies of Prophet of Kruphix on the field, then you can stack both the triggers for their effects, untap all of your lands using the first trigger and tap them all to Flash and Cloudstone Curio as many creatures as your mana allows before the second Prophet's effect resolves and you untap your lands again.
Kiora's Follower could be a useful card for the deck, since he can untap lands when you're attempting to ramp and Arcanis the Omnipotent when you just want to draw your entire deck.
