How to get these pets?

[Alexios]

I am looking to get old heroic and arcane pets like Heroic Timber/Precious/Gobi/Lucky and Arcanes like The Brothers Whim, Mishi etc.. basicanly the pets that Egg Zav dont drop, were not available at egg vendors and are not getting included in the event chests this year.

How are the new players and collectors going to get all these old pets?
Why not add these pets to the game as rare loot? Or add these eggs to the mini events?

Idea: Add a new game mode like "Elite", where all maps scale to the same difficulty as Timekeepers (elite maus). And then add these old eggs to those maps.
