Golden Pharoah dog has its uses depending on your other available toons. Its passive reduces damage by 35%, so it is a partial blocker. It's normal move has 50% chance to cleanse one negative effect on allies. Its power move heals the team and gives 50% chance for golden immunity.

Angel talisman is a great choice to keep him from being stunned. The energy talisman is a good choice if he cant do his power move you may gain/steal power. Against multihitters power talisman may be an option. He is pretty tough and angel gives additional 5% heal.

Was he nerfed? I thought he gave immunity 100% of the time. When I first got him, before angel talisman I used immunity on him. He was part of my BNW teams before the new super OP toons.
