flabebe would be Grass Floette - Grass Florges - grass/ psychic
Carbink - pure rock
Xerneas - pure steel or pure grass
Feel free to add the fairies I missed or change the ones I listed.
At first when I saw the two legendaries I thought Yveltal would be FIre-Flying and Xerneas would be Water and maybe something else like Dragon. Since I saw that Xerneas jumped really high but didn't fly, I knew it couldn't be Flying.
