Depends on your goals.

If you desire a soundwave evolution, which is the only card worth evolving if you have a decent deck,  then use them on him. From there you will need to get lucky or buy two more.

If you desire a hing ranking in addition then chain him in the battlefield 10 for 2 million. Be prepared to spend some battle cubes however now that they "corrected" the attack strength of the bosses.

If you want to stay free and garauntee you get laserbeak of which you got two for free, use them on him.
