I have two GXs (please don't hurt me, I just started actually collecting for the TCG) and they both say they are Promo cards. They are a Tapu Koko GX and a (kantonian) Raichu GX. They both have a 2017 copyright date, and both have, instead of a expansion symbol, a black star with PROMO on it. But when I look at my 3 EXs, they just have normal expansion symbols. Are any of these cards rare, or normal? (btw, the 3 EXs are c2014 Mega-Manectric EX, c2015 Tyranitar EX, and c2015 Mega-Tyranitar EX. The Tyranitars are from the same expansion, it looks like)
