If you didn't want to be as greedy, you could also play Split Decision to get with FF with the upside that a lot of the time it can target someone (you or your opponent's Dig through Time). I want to run 3-4 LDV, and probably Lotus Petal to really maximize LDV (Petals make it more likely to negate the cost of your cantrip by using Brainstorm to find combo piece + petal). As an interesting aside, Petal really opens up the Mentor splash.
