I thought there was a chance of making it to Silver today but I am in a bit of a rush so I can't stay and battle some more. I was pretty close to promoting after completing the quest but got beaten back down in the post quest battles.
Pretty confident that it will happen tomorrow. Sometimes it is just luck what sort of opponents and rules you get assigned. If i get either the Water or Earth splinter, it will happen. If it is the Life or Death splinter, it will be painful.
Now for the rewards which are just kind of sad today... 2 credits. Can't wait to not get credit rewards in Silver. 7 days is a nice time to promote if my memory serves me right.
