These are all great cards. I am working on getting all of mine to max level ASAP. I got Grum Flameblade there already. I saw the writing on the wall and figured that this card would be much more expensive in the future. I wish I could've afford more packs so I would've gotten more in the airdrop, but I did get two, which is better than a lot of people. Now when I get that card in a pack, I am hanging onto it.
I've learned some lessons over the years. One is that I'm better off not cominbing all of my cards all the time. I've got some at max and higher levels that are good to rent out or play, but then I'm going to keep a lot of single cards on hand in case I want to sell some of them in the future. When I do feel like selling cards, I have a tough time because they're all combined. The only way to sell them quickly when they're combined is to undercut the per BCX price considerably.
