Skill swap Gardevoir

[Blue_Flygon]

Im wanting to use mega gardevoir and skill swap with greninja so she gets protean. Then have her use thunderbolt so shes a electric type and then u-turn out greninja into furfrou and use skill swap so she has fur coat. Would she still be an electric type mega gardevoir that has fur coat or would her typing revert after losing protean?
