On the process of completing my quest, I now changed from Silver I to Gold III which is a good achievement for me today. It takes a lot of battles before I manage to make it to this level. But it seems that experience does really paid off as I gain a lot of strategies.
Opening the quest chest, I see a lot of potions this time which I think I can use it for tomorrow's chest, giving me more luck on getting better cards. As for my acquired card for today, it seems that Etin Spearman is quite a good range attack while having 8 life.
I did a couple of wins for today compare to yesterday that a successive loses which I nearly get back to Silver II. I got more than 50% winning rate for today which is a good level up for my way of playing this game.
Now looking forward to tomorrow's run whether I can have a bit of good luck or not.
