I redid the troop formation that Gunmuse recommended and dropped the Artillery. I rejiggered the troop values and such and I think that this is a better formation. It is for me anyway with the stats that I have. You can change it as you like. I recommend Anne & Gaston for Guards. I also recommend filling in all the unused troop levels with 1 troop each for everything. You can even do the Artillery, it does boose the score.
The Airship is configured the same as it would be for Attack/Defense that Gunmuse recommends.
It is also set up for T11’s. If you have T12 or something else, your mileage may vary.
