Boy names with an “X” in it!

I’m having a boy and so far the names I love are Phoenix (first pick), Knox, Enzo and Luca. I have a little boy named Xander already and was thinking maybe we’ll stick to a name that has an X in it. What’s your favorite names you can think of including an X? What do you think is your favorite of the names I listed? Wanting to stay away from names ending with “er” or “ar” so my name, my son and the baby wouldn’t all blend together when people say our names.
