Notes
Heavy game, ~1,749 cards across three sizes. Two independent guides agree: 727 standard (63.5x88) + 975 mini-euro (44x68) + ~47 square monster-stat cards (102x102). The 102x102mm monster stat cards have no true off-the-shelf sleeve; Large Square is the nearest named size but is oversized, so many players leave them unsleeved.
