Notes below are mostly for my own reference:
Week 1 - 7 wins, 3 losses. One loss, I just got out-played. One loss, I never drew a 4th power and my opponent got all the power and colors he could have hoped for (and didn't flood either). Final loss, my opponent had a Jawbone Greatsword, which he tributed for Brand, and he used the sword to clear my Intrepid Longhorn; later he played the Brand, gave it unblockable with Reconaissance, and played rampage on it for a casual 26 face damage -- this situation cannot be beaten in any reasonable world (unless maybe if I had drawn an Edict of Grodov, which basically would have delayed my demise for a couple turns and made him waste two cards ... but he probably still wins cuz Brand).
Week 2 - 9 wins, 1 loss. The 1 loss was 100% my misplay. I killered into a 7/7 lifesteal flyer to get tribute to silence that flyer ... but I could have killered into a different unit to get the tribute. They healed for 7 - when I lost, they had 6 health. So I lost entirely due to giving them 7 free healing. I had a reason for that killer attack at the time, but I was a very weird and incorrect reason. Sometimes I get my brain tied into knots and miss obvious things. Oh well. 9-1 is very good. At time of games completion, I was rank 17. 16-4 after week 2.
