@shizzlemetimbers is also a big Gyarados fan. Here is his collection thread. I guess it all comes down to whomever adds the SNAP Photo Contest one to their collection first. I wish I had the Pikachu for my collection, but I’m afraid that if it ever pops up at all, it will be way above my budget (in the range of 10k+ USD). 
Anyway, welcome to the forum, and I’m looking forward to the pictures of your Gyarados collection.
