Wish I would've read those posts before the event ended! Nice find.
Regarding air, I think this strategy is super powerful right now for TH9-TH10 -

Working on getting a LH (then upgrading it to L2) and upgrading loons to L6 and probably get haste too, in order to move to this attack strategy.
I see so many valk strats at TH9 but I think L4 valks are too weak (these attacks never seem executed as well as the lavaloon or gohowiz type attacks). I currently gohowiz, usually 2 golems and 26 hogs, with bombers/wiz/a witch and a few archers (4x heal and 2x psn) and I can 3 star many TH9s with max defenses. The ones that are well designed, particularly with heroes on the inside, are still too tough for me.
