Facebook has some buy/sell/roll groups that you could look into. If you sell at a con, you'll likely only get up to 75% of the value, which on a card like that is substantial. Cardsphere is also a good spot and also could facilitate a trade if that is something you are interested in doing.

I did like season 4. I'm not a big fan of the multi-year trend from season to season for shows, especially with kids. If you're making a show with all main characters being teens/kids, you need to have multiple seasons ready to roll just in case. It's been so long between I just kinda lost interest.

I feel like I'm going to watch the season out of obligation at this point, but it is definitely not a top priority for me.

Super cool lore behind that character too!

Mine is in the mail. How is the book? Is it magnetic or anything?

Two-Headed giant would be pretty fun too. It's been a while since I've had a chance to play.
