I guess he could be a good pack-in with the Man-Thing, but there's a high chance we'll be getting it in the new Wallgreens wave, so that's out too. I guess you could just repaint him and re-use him in an All-New All-Different Wave if it happens, but to me, he's pretty much a one-and-done character.
Man-Thing will ALSO get reused. Same logic. So those two together make sense. Maybe in a four pack of unusual characters to get us someone ELSE with new tooling. Maybe Man-Thing, Howard, Dr. Bong, and Machine Man or Uatu even.
