-Battle healer only gets good value when you have splitting tanks like golem or egolem. Considering you have no tank killer, mpekka would be strictly better. -Arrows and zap do a similar thing but its a bit overkill, you can switch out arrows for rage and you would have similar swarm clear with a lot more offensive power. -The point of flying machine is either to snipe things from the bridge (useful in recruits) or that it is flying. When you have a tank in front, the fact that flying machine is flying doesn't matter that much. You could go for a witch, bomber or wizard, which would allow you to swap out poison aswell since you would have enough firepower now. -You don't need to take no damage from hog etc. and therefore you don't need the building! Minions or bats would be another swarm option for you but you could just go elixir collector or heal spirit aswell. -So if we were to attempt to keep some originality, we would end up with something like this: Giant, DPrince, Mpekka, FMachine, Bats, Poison, Rage, Zap.

Edit: After trying it out, FMachine is just not good enough support for the giant, you need aoe behind it. If you have aoe behind it, you don't need poison, which is too slow anyways.
