Two questions

>First
I heard that rolling for the kitasan black card right now is a trap cause it "wont be on best rate up banner" which will be "coming not too far from now." Is this so?

>Second
How do alternate characters work? Is pic related a "second" Gold Ship unit that I roll for, or is it like a skin I buy with money? Also will it be coming relatively soon, cause i'd rather save for it now, if it's a unit.
