i have an LTR keldeo
ad which black kyurem ex are u wanting im assuming black ballista
OK it looks like ungraded Kyogre Gold Stars are between 35 and 45 from what I can see. 55-60 seems the norm for the festivals.
As for the kyurem, it's whatever one is in LTR. I think it may be black ballista. Valuing Keldeo @ 9 and about 7 on BK
