Who would you pick from this selector?

The way I view it is this way: unless you really want a specific champ (in which case you should of course pick that one), skip every champion that was in a Reunion or Gifted Guardian crystal. I think those are already in the basic pool. I would then go for one in the crystal pool that you're least likely to get champions from. For me, I don't play Incursions aside from when it's part of a side quest, so I basically never pick up champions from that crystal pool. If I got one of those selectors, I would therefore probably pick up someone from the Incursions crystal, and if I remember that pool correctly, I think Hulkbuster is in it which is someone I'd really love to pull.

But if you don't like AW, maybe the loyalty crystal pool is better to pick from for you.

Or maybe you just really like a champ from one of the other pools. As I said, picking someone you like isn't a bad option at all. It might even be the best option.

Personally Cap IW. But so I could awaken him
