Trade Stack 21: Another Shiny - It Won't Last Long!

Here is how this works:

Every so often (i.e. whenever I feel like it), I will add a card to a "Trade Stack".  Whenever the stack becomes appealing enough to someone, that person needs to comment on the post saying they'd like to claim the stack AND tell me which card they are sending off of my want list.  That's all you have to do - trade me ONE card (or more, of course) card from my want list for the entire stack of cards that I'm offering.  Each time, it will be first come, first serve...so act quickly (unless of course you are a gambler and hope to wait it out until there are 10+ cards in the stack that you want in exchange for a single 2004 UD Vintage card that I am looking for)!

The Trade Stack:

Earlier today, I detailed the breakdown of the first twenty trade stacks team-by-team.  Amongst the various observations that I made was the fact that I need to increase the number of teams represented by insert/parallel cards.  To make good on my observation, here's a shiny insert of a Kansas City Royal - I don't expect this trade stack to last long (at least if all the other trade stacks with shiny cards are indication).

Want the card(s) in the stack?  Act fast - tell me which card you will send me off my want list in the comments below!  If no one claims this card within a reasonable amount of time (a few hours up to a few days, depending) - I'll add another card to the stack and the process will start again!
