My final haul after fusing a bunch of Minas, Selinas, and two Milagros:
I'm pretty satisfied with what I got, considering what I gave up.
I did try to fuse 2 4* Glebs together just to get a Dragon Jelly, and I got a new 4* I didn't have before, but I honestly didn't expect anything good.
I just don't see any other way to make a Mina or Selina as useful as Fusion did. I was addicted to buying cheap Minas from people, and now I have some really nice cards.
