Did anyone come up with a good use case for Hatters Reserve Relics other than the HP Nukers?

I do not have any of the Meta HP Nukers, so I can't put them there, although I suppose I could throw one on Nick since I am gonna try to build an unkillable Sacred Order Siege Team.

Other than that, they seem like they might be okay on Rotos (Have) and He-Man (Don't Have), but I put a Golden Elixir on my Rotos since that seems like it would synergize well with his passive.

I have started using these as upgrade materials for other Relics, but once gone, they are gone for good, so just wondering if anyone found a good use for them?
