Absolutely. I would. Great IV's, best moveset. He'll get plenty of use considering Dragonite might be most common gym defender in the game. I powered up 2 of them just b/c.
He makes easy work of them, that's for sure...and it's not like when you need more help you can just go to the Lapras field and pick out another.
Not like he's a niche hero you'll barely use. That guy will see battle...and plenty of it!
