This means that if you were to draw a Pot of Greed in your opening hand - something that the players of the 2003-2005 World Championships had a 12.5% chance of doing, as it was limited to a single copy per deck - your hand size increased from five to six and your deck size reduced down to 37, increasing your chances of drawing a specific card from 33.76% to 42.15%
Impressive number of cards that make me want to play and build tribal decks from this set and lovely to see some of the lesser tribes getting interesting pushes
