Conquerers of the Sea - The new Blood of Humans?

Communion Packed Orb Lightning and Thunder Strikes along with Air Elementals (With how the game uses gems now, you can get the most out of each Elemental summoning for 1 Gem a piece if you use Communion).

Also don't forget Cloud Trapeze as well as easy access to large #'s of Flying Units. The ability to Communion makes the lack of a pure 3 Fire less cumbersome to overcome, but unless you get lucky you will more than likely have to wait a little longer than turn 10 for Flaming Arrows (the benchmark for Marignon).
