Circle of the Dragonshifter (5e Subclass)
From D&D Wiki
The path of sorcery isn't the only way to attain control over one's draconic ancestry, there is another, albeit more ancient way. Those of dragon's blood following the way of nature can unleash their power in ways considered heretical by their druidic brethren, but nonetheless this strength can be a force to behold.

You may swap any chosen mutation for another at the end of a long rest. You gain the ability to choose a second mutation at 6th level and third mutation at 10th level.
