Hmph, no ranged fliers. Allright let's see what we can cook ...
Steam Gentlemen: crazy industrialists and big game hunters.
Specialize in mobility. As well as trophy hunting. (Rocking out, Foola, Croakamancy)
Diwigible (yay!) 42 Hits, 40 Attack, 2 Defense, 4 Move, Type- Flier, 205 cost
Otto Motor: 15 Hits, 14 Attack, 1 Defense, 4 Move, Type- Flier, 43 cost
Steam Plane: 10 Hits, 1 Attack, 9 Defense, 4 Move, Type- Flier, 35 cost
Wion Hunter: 10 Hits, 7 Attack, 3 Defense, 2 Move, Type- Archer, 18 cost
Awwtilewy: 12 Hits, 9 Attack, 3 Defense, 2 Mover, Type- Siege, 24 cost
Commander: Lord Wivingston (Croakamancer/Rocking out): 150
+ 1 Diwigible, +1 Steam plane, +1 Lvl 1 scout = 400.
Stack: Diwigible, Steam plane, (Scout, Wivingston)
The Diwi is not the most cost-efficient unit around when air battles are involved, but hopefully for a few bombings of Gobwins or base defense, will be adequate.
The whole point of this is lost if you keep it a secret.
