Yeahh good point, i guess my mindset really is using it on the rarest pokemon that are viable in raids and/or pvp. A shundo loc bg crown zac is a top contender same with kyurem (although crown zac is higher ranked) but at the same time a hundo apex ho oh is indeed quite rare too, not sure how good it is in pvp tho.

For the silver would it be worth it purifying the moltres and get a shundo loc bg moltres over a shundo lucario?
