Ruling Primes and normal Pokemon

[BM1014]

I didnt play for a long time, sorry for the following for noobish following 2 questions. :X

1. Can I have 4 Gengars and another Gengar Prime in a single deck?
2. Can Gengar Prime lvl up into Gengar lv.X?

 

[King Arceus]

1) No because the name of the card is treated as Gengar.
2) Yes because the card is treated as Gengar.
