Pick your cards in the following rank:
Bombs
Removal
Evasion
Attack
Denial
This is the so-called BREAD rule. I had some bombs and lots of denial, but next to no removal, very little evasion, and barely enough attack.
I pulled a god card, and I should have used it in a mono-blue deck. I even pulled it in my opening hand in both games of my first and only match (I needed to return to my busy life after that).
