Morgana was the queen of the Earth fairies--you wouldn't put someone weak in charge. She also helped put the Wizards away once before, and sought to seek revenge and destroy them when Roxy released her and her fairy warriors.

Selina isn't that strong. She's a freshman witch and never even got any real training and practice since the Trix took over Cloudtower before she had those chances. And if you took the Legendarium away, she'd be nothing.
