I was thinking of a new troop that involved the air and ground aspects of the game. For example they could have a hog with wings that has a rider on top. They could make the hog (which breathes fire) target defenses, while the rider sits on the hogs and waits until you activate it (just like the hero abilities) and then it jumps off and attacks everything. I would give both the hog and the rider the same stats as a hog because the hog would be taking shots from the air defense and the rider would be attacking other buildings besides defenses. Supercell could even do a major add campaign with the witch and archers saying I'll say hog rider when pigs can fly and then whoosh! A hog rider comes in on his flying hog and battles. Or we could have some type of troop kinda like a balloon (slow moving) that drops other troops (or spawns like the witch). I'm imagining this troop targets th's and slowly moves dropping troops like skeletons, archers, barbs or even wall breakers until it gets to the th to deal damage. This troop would mostly be used as a tank troop because the defenses would all be distracted with the balloon type troop itself or the troops it's dropping.
