skyridge booster box you get one of the rarest and legendary Pokémon booster packs you can get your hands on Skyridge - Booster Pack

I love this at multiplayer when you have a few options, and with Mana Rocks and Lands that can make any color of mana, because getting any color of mana from your Dimir control brew that grabs a red activated ability is pretty valuable, so run this with City of Brass and Darksteel Ingot and Fellwar Stone

Like most Pokmon cards, the value of Vivillon depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (BREAKthrough)

Thanks to having access to black, Golgari has plenty of the best sacrifice outlets that let you do so for free, such as Viscera Seer and Carrion Feeder

If you can benefit from that situation with a Fecundity or something, go for it, but this seems like its hard to benefit from and 8 mana spells better win the game almost on their own
