It will pretty much hard counter any air units. Judging by coc stats, it would deal like 5x damage of musketeer and even when used against ground troops it could be smt like goblin cage, to tank and kite
Not enough air cards and air cards aren't used enough. If lava hound got a buff, then maybe. Also, it would have to be overpowered. A wizard tower... now that's a good idea.
