I'm trying to understand what just happened...
As always, enjoying the game throughout the day, trying to get some wins under my belt as well as finally getting to the point of completing the quest. Finally, the quest was completed, and chest were being opened. A few potions, a few low amount DEC, and a couple of much seen cards were inside these chests, until a card pack appeared.
Opening a card pack with 3x Alchemy and 4x Legendary potions available isn't what I'd do normally, yet I did. Look and behold, I've was lucky enough not only to get a Lir Deepswimmer but also it being a gold foil card (which is not in my collection nor do I rent it yet).
Lir Deepswimmer - Legendary Water Summoner (Untamed)
Card which was my best gain from a card pack prior to receiving Lir Deepswimmer was Yodin Zaku.
I guess, you can say this was one lucky moment!
Thanks for stopping by and take care!
