I made some dumb mistakes early and started leveling some common cards after getting Iron Monger maxed out because I had no other cards I wanted to level. Once I got Annihilus, I didn't do that anymore though its taking FOREVER to level him. I wish I had those cards I wasted back...I'd like to get him done so I can move onto other cards damnit! Debating just using a ton of ISO-8s because leveling 40-60 is sooo damn time consuming and expensive getting all the uncommons...
