I don't think so. Oppression may be more playable, but she has a much better effect and you don't have to pay anything. Shes an automatic plus 1 and she stops Gorz or Tragodia from hitting the field. So no in a nutshell she gives more advantage than oppression.
... Kristya was thrown out as a suggestion for the deck. My deck.
Can I still use Shining Angel when I have Kristya on the field?
Can I still use Oracle of the Sun when Kristya on the field?
Chaos-End Master?
Chaos Sorcerer?
Dark Armed Dragon?
Tragoedia?
No, it can't. And being that there are only 6 Fairy-type monsters in the deck overall, with no two-turn method of getting them to my Graveyard, how do you expect me to work Kristya into the deck? Splash a Foolish Burial and a Call of the Haunted?
I'd rather make full abuse with Royal Oppression and be able to perform most of my Special Summoning while hindering theirs. It's overall the better choice for the deck.
Start thinking plox.
