Hi bro :)
Hive will come back up in the future but this is a good time to convert my liquid HBDs to HIVE.
Chaos Dragon is a card I like and I want to take it to at least level 2 because it gains the blast ability and in battles with lots of mana it's a great card to deploy.
I did not know Avenged Sevenfold and as soon as I have a moment I will listen to them...you have me curious.
For Rising Star the ego is too high and you'd better buy tool cards to get more skill points from music lessons.
I wrote a post in the past about the Ego that I hope will be useful ;)
