A/N: Next Chapter qill be Harry and Crew's Decks, namely Harry Potter, Ronald Weasley, and Hermione Granger. Now question. What theme should each member of the "Golden Trio" have for their decks, and what should their best monster be? I can't, and i mean can't update until I get ideas for each one. It's not that I won't, but that I'm drawing a blank and need help. Until then, barryc10, signing out.
