In my world a Magic High Nation is fighting against high tech level Nation about the same level as one of the nations in our world. I'm trying to decide what sort of magical creatures can replace a modern air force and make the magic side able to stand up to Modern military weapons.
Note : The conflict will be mainly a guerrilla war in forested, mountainous environment with some spill over into the cities.
As a guerrilla general fighting for the magic side, I can only afford to choose two magical artifacts each of which will give me power over one of the two magical creatures below.
Which combination of creatures would be most effective in closing the gap against a nation with a modern air force?
