I think Textures might be the closest-but-not-yet-bingo of all the cards. It feels like it's up every day yet ... nothing. Since I think half the players are playing Textures, that would be a massive win--I'm rooting for it for that reason! Then there were two possible BINGOs on Maglor in History 1, the only card (to the best of my knowledge) so far, and it doesn't feel like that one has been called nearly as often as Textures.

Lady Probability, thou art cruel. :)
