It's not out yet. And yep, events work somewhat like that. Event pokemon mean you can't find them multiple times in the wild.
Metagross
Meteor mash, bullet punch, hammer arm, zen headbutt
Lucario
Hi jump kick
Blaze kick
Crunch
Bullet punch
Or power up punch or swords dance for attack raise
Make them both adamant.
The lucario moves are egg moves. You know about them I hope?
