So, since the new update Aigis has invented the Barrack which can be used to store units for later use... AND also the BLACK NANALY which I very much would love to get if I could. Question is, which is better? To max out the storage or try out my luck to get nanaly? I expected more people saying that storage is better but whatever, I just want to hear your thoughts.

Edit: I currently have 50 unused SCs :3
