I received a Venari Crystalsmith (Rare Life Monster) as a daily quest reward (2021.09.14)
Still not Legendary, but at least a card, and it is Rare.
Currently there are only 2698 Venari Crystalsmith cards in circulation.
This card is currently valued at $3.50 USD.
Finally something good and valuable instead of the worthless Legendary Potion Charges.
By the way, this is the first time I see (and hear about) this card.
