Quick context: All I give a fuck about is finishing fucking Alt Arena once, while minimizing further pain and mental trauma. With the team of Gronia/2 Rags/Nees/Odindrag, I have gotten to Metatron or Kali several times, but never in condition to seal the deal. I can get Yusuke from the Exchange if I sacrifice my only Ryune, Baldin, Aten, and Blodin. There are other units on the exchange I could use, but those 4 are the ones I could probably part with most easily. My light box is pretty big with 2 Yunas, 3 Paimon, Roots, LHeradrag, etc. Would Yusuke be an improvement for me in AA, or should I save my cards and continue killing myself for one run with Gronia?
