I was playing the base game and expansion with my wife and kids today and we were winning pretty handily. On my turn I drew the Goblin King as one of the monster tokens. One of the three extra monster tokens I drew for the Goblin King's special power was "Draw Four Monster Tokens". And one of the four tokens I drew was "Draw Three Monster Tokens". So a total of twelve monster tokens drawn on one turn. We still hung on to win, but just barely.
