Elder Kais is the only way for him. He is very good and indeed worthy, but only if he is part of your main team and rotation, like Extreme PHY or Extreme team. Other cards should be priority if you have better cards.

You can use an hourglass to reverse him and use dupes on him, no need to dokkan the dupes.
