Just unlocked her at duel world 6 for 5ds world but You only get access to black rose dragon by using her skill looks like all the ace cards will be locked behind a pay wall thoughts?
Next main box :
1 black rose judgement
2 black wing scale
3 power tool techonology
master
4 ancient fairy bless
5 red dragon's wrath
6 infernity doom terror
They're strong enough that they deserve to be pack cards. It doesn't bother me for anything more than flavour reasons. The skills make up for it flavour-wise anyway, just like the justification for Para and Dox not having Sanga, Suijin and Kazejin.
