I was worried about that with bossk.
Boba and cad are already set with shards, with ig88 I have 104 shards, just not activated and I hoard squad arena credits, so he should be easy. I can spend all my cantina tries on aurra. Dengar always seems to be in my guild store, that's why I mentioned him. Mando is always in shipments and I have him at 5 stars. I suppose I could sub out dengar for bossk, would take longer, but if he's needed, that's fine. I save my crystals for when there's one specific thing I need them for. So, Boba, ig88, and aurra would just be a matter of a couple weeks of spending all my stuff on them at the same time. Cad is just a matter of activating at 7 star. Mando would be the outlier since I would need to spend crystals outside of the 5 tries a day. Bossk of course the toughest, I would need to use crystals outside of his 20 points per try. Would Boba, ig88, aurra, cad and bossk be a reasonable option given what I have?
