Man I really wish I watched this video before I did the first 3 Deckathalons (Myth, Life and Balance for the account I'm playing on). One small point I'll add to the 10th question about Maycast pets, it is worth unlocking frozen kraken as soon as you get it provided you have the talent tokens. This is because once you unlock Frozen Kraken on that pet, it is unlocked for any character you transfer that pet to, not just on that one character, and also, any pet that you hatch from that unlocked Frozen Kraken pet will also have Frozen Kraken already unlocked if it manifests it. That way if you have the tokens but your heals aren't perfect, you can still use the willcast pet while working on making one with the optimal heals as well.
Sorry new here to deckathalons and I have an issue with crafting the decks. So I have 3 deck 1s and 1 deck 2 and was hoping to craft deck 3. Do you have to craft them all in the same session for the deck to show up? I hope I explained that okay.
