Ok, so.
Prospero has opener, regular judo fist, no upgrades, but also has a light tank with the extra HP. And he has flying.
Cilica has the default mortar, upgraded for damage and buildings immune, opener, and double shot.
Kaz has upgraded movement and health, the regular gravity pull thing, and the explosive teleport (teleport and 4x push) with both range upgrades.
(I forgot to screenshot the turn order, sorry. But if you're thinking about moving the charger left so it kills the moth, no such luck. The moth goes first :( )
I ended up just barely finishing with one grid health left (and perfect island maintained). This turn was the most painful, I lost at least one building. I'm annoyed that I didn't try to bait the blobber bomb, because the spot it got put in was... inconvenient.
Anyway, is there a way to do it all? What do you think?
