Acquiring new 2* and 1* champs

Are the crystals in the misc. section of the store the same (2*) champs as what’s in the PHCs?
I’d love to expand my roster for things like Variant 4 but am not sure the best way to go. Is there a list of what’s in the PHCs?
How do you get the others?
For example I’d love to use Wasp on the crit path in V4 but don’t have her in my 2* roster
