GlanDuGlad to see a topic about the true deal.

Just 2 point :

You can have guaranted firestarter at each rotation, so its irrelevant to count how many F4 before using fire.

The refresh of despair is really important.
Using convert after it, it can be used in place of F1.

For the opening, I do :
F1»firestarter>ley line>F4>F4>triple cast>F4>F4>F4> instant cast > despair > convert > F4 > Despair > B3 > B4 (0 manacost)

The purpose of the opening, no F1 between the F4.
