Y'know... I had a Deck that was likely to win Worlds. Unfortunately, I didn't pay for any lodging in advance like everyone else, so any lodging that was available just a week before was soo expensive, I couldn't afford it, practically. Travelling wasn't a drastic issue as I live in Washington State and can drive there. I considered camping near the Vancouver Convention Centre, but dad warned me that sleeping outside like that is quite illegal (which would mean homeless folks are constantly breaking the law. I honestly am not convinced). So at the end of the day, I completely missed Worlds, despite having a tough Deck.
Also I hadn't packed up all my cards. Some of them were miscellaneously lying around the table
My Deck is Garbodor with mixed EX's: Landorus EX, Cobalion EX, Victini EX, Mewtwo EX. I teched in 1 Cobalion NVI.
So hey, every good Pokemon Trainer needs to have 2 or 3 Pay Lodging in Advance, and Pack Up and Travel Early in their Decks.
