How it will works:

Like normal dragon just with wizard on his back. Wizard will sit on the dragon and will throw fireballs, dragon will spit the fire at the same target like wizard so the damage will be very big and damage type will be area splash. With lava hounts and baloons it will be very effective becasue lava and baloons will destroy defense and dragon rider will
destroy others buildings, alternatively can help in the destruction of defense if it is near then othrer buldings.
