Primeval Hoard Pack

I have two accounts with 11 wizards total that I need mounts for out of this pack for the set bonus.

I've heard to wait for the Pack-A-Palooza event, or the super primeval event, but it seems like these don't happen anymore (Last time in 2019 and 2023 respectively)

Is there anything to wait for? Or should I bite the bullet and buy a ton of packs?
