Except, Victory Medal WAS easy to get. Winning a Battle Road really wasn't a tough thing to do until this year came about.
I'm all in favor of making Tropical Beach a little less exclusive. Two of the best decks in the format right now have to run it in order to actually work, Now, while it's not a necessity, as there are other deck choices, those two decks are far too costly to run, which limits the options of everyone that can't obtain Tropical Beach. I myself cannot see why it would be an issue to make a reprint of it, as they have reprinted a Worlds promo in the past - Tropical Wind from Worlds 2004 - and it was near unplayable.
I get that some want to keep it exclusive, as those that earned it can treasure and feel like they've actually earned something worthwhile. I can relate to the feeling; however, I don't feel that this one card should be kept exclusive because it was a Worlds promo. Everyone should have the chance to obtain even one, so as to level the playing field.
