My new mythics

Hi there!
Im a new player and with the event i have got 2 mithic monsters: Flowertail and Reindra
Are they good? How can use them in a team?

Earth mythic is bad , don’t know about the other

The mithics are these two

Flowertails is good, other one is bad cause everything with protect was nerfed significantly, flowertails is good FL or 5th place mon
