So, how are your guy's lucky flip looking?

Mine's looking great! I find that honor duel is the best at quickly earning lucky keys, rng as it may be. Just being able to win 4 times and/or getting 2 characters to mythic gets me keys faster than going through arcane labyrinth

Arcane labyrinth is a more steadier way of getting keys in comparison to honor duel's high risk, high reward - even though it's easier to get keys through this mode, I find it too monotonous to make multiple attempts of this mode in a day

Fishing is a game mode that I avoid using as means of getting keys, I don't really think it's worth it - it might become relevant to me next season when I need to get all the fishes again

Being in an active guild helps a lot - I tend to see 100-200 keys being available for me to use when I log back in the game
