Enchanted creature gains +2/+2 for each dragon you control and "dragons cannot attack you or deal damage to a creature you control,"

When enchanted creature dies, each dragon gains +X/+X where X was its power and you gain control of all dragons until end of turn.

"Seriously misunderstood creatures dragons. They love music and are loath to harm bards or minstrels," -Darian Dragon Lover,
