Fire 9 blessing is good counter (as mentioned by Norfleet) against VQ. Most nations have enough affordable holy troops that can be blessed to do fire damage that will ignore her etherealness and protection.

For example, Moloch is both great SC chassis and counter for VQ due to his blessing effect. You can equip with pair of armor negating/piercing weapons and, if you can afford, pendant of luck and/or boots of speed and tell him to attack fliers. He will engage VQ on turn one and should be able to kill her before she buffs her self (unless you are extremely unlucky).
