Would be nice if one of them could function as BF 5-8, then I could replace Astrolab (and work on the mana extensively) to make the combo more solid (along with Enlightened and Infernal Tutors)
So did the math on this and actually Breakthrough does work as Brainfreeze 5-8. Since Breakthrough puts 4 cards in the grave and only costs 1 it pays for itself and add 1 extra card to the grave. After casting it 3 times, you have enough cards to exile to cast LED and repeat the process. Do this enough until you find Brainfreeze to put a whole bunch of cards in your grave and then just loop Lightning Bolts FTW.
