After a bad day yesterday trying to complete the daily quest with a fire splinter deck, I got the same luck today about the given quest. Also fire.
I could've requested a different quest, but no, I continued with Fire. And it was a good choice!
I don't know if I was more inspired than yesterday or the choice of opponents was more favorable. Judging from their ratings, I'd say the first one is true. So I managed to complete the daily quest rather quickly.
And here's what I've got inside the booster pack:
Now I'm going to check if I can upgrade anything or if I have the funds on my SM account to buy the cards I want from the market.
Wish me luck!
