We did this last year - and it worked out well. I decided to try it again, with a fresh thread.
My son (9) has a complete set 1-60. He was hoping to get a complete 2nd set (1-60) so he could give a complete set to his cousin for Christmas. To do that, he needs another 3, 8 and 12 card. Those are “Star” cards - only 1 of those come per pack - so they’re rare. He has an extra #9 (Lytho’s Rock Titan Boulder Throw) and 2 extra #17 (Simba’s Roar) that he was hoping he could trade with somebody who needs one or both of those, and who has an extra 3, 8 and/or 12 to trade.
After that - he just has a bunch of extra cards he asked me to help him, though TP/Forum, to get to kids who are trying to complete their own 1-60 sets. His primary desire is to help others get complete 1-60 sets - not just his cousin. If there are other kids out there who are missing cards - PLEASE let us know. We have extras - and we’re happy mailing them to you to use as stocking stuffers, etc. He’s definitely into the “giving” part of the Holiday Season that way. Please don’t be shy. If we can’t help, I’m sure other Liners would be happy to.
Now for the “Dad looking for stocking stuffers for my son” portion of this message: My son is still working on his Lightning and Party Cards. He doesn’t have any duplicate Lightning cards, but he does have some duplicate Party Cards he told me he’s “saving to trade to fill his gaps.” Therefore, I’m sure he’d be fine if I were to trade Party Cards on his behalf. My top priority would be to send a 2018 X-Mas Card to somebody who doesn’t have one, but who has an extra 2018 Halloween Card - as we could help each other out. If you have Dupes of other Holiday Cards, let me know that as well … we usually turn to eBay to buy a few for him at Christmas but if we could save money and help out other Liners via trades, that would be awesome, too.
