Nobody will play Blackwings bc it requires 3 Bora and 3 Whirlwind, so three runs of a 🔥 old box. New players won't farm that, and old players don't have gems anymore.
Everyone who wants to play Blackwings would have farmed Bora and Whirlwind already.
And cards being in old boxes never stopped people. Remember when people farmed Babycerasaurus to play Survival's End deck? Or what about Yubel Nepthys deck?
Mini box are more suitable for Infernity. Blackwing is a fan favorite archetype just like Heroes, they will use it as moneygrabber by putting it in a big box and structure deck
