Well, actually it's more like the week after St. Patrick's day 5 of 7, or if you will... the hangover 5 of 7. Here's a hint, you left Dilate on the roof while you were high on Miracle Fruit.
This 5 of 7, no grand prize. You get the usual 5 Point cards if you fight in Folrart or Crest on 5 of the 7 days from the 19th to the 25th. IN ADDITION, if you complete 10 or more duels during that time you will get a copy of Explosion Artist / Mesrag, the official Alteil card of hangovers. BUT WAIT, there's more. Accumulate 5 or more wins, and you'll get a copy of EX: Abyss Centaur / Dical, who -- has nothing to do with hangovers or St. Patrick's day, really -- but he can drink like a horse.
