Chances are, for cards which are still in the New Blood pack (i.e. Dante), prices will go down, however for older cards, the prices change far more slowly, if at all, so I don't think you stand to lose much from buying a few Piranas and, if you dislike them, selling them back again. You can always make back some quick clintz in DTs .
Yeah i geuss it most depends on how usefull they are,..
they dont have a cr's so mabey if you keep on of 'm might
be the next collector card,..
i've got all the pirana's except for that new one
and they are a nice clan deffinatly, as mono
but also combined whit other clans, most clans
can make great use of the pill diffrence you can
creat with the piranas
