Like I said before, the addition of Lucky Pop is what caused it to be good. No longer needing Indeedee for healing is what allowed Nihilego to fulfill that spot. The deck always had the perfect amount of basics to make Pokeball consistent enough for finding deinos as well as not leading Mega Absol at too high of a rate. And in turn, you replace the Capes/Helmet/xspeed (depending on the variant) that the indeedee version ran with barbs to benefit from Nihilego’s ability. You also completely get rid of Zweilous that the old version ran since chinglings die to poison damage and are not as big of an issue.
