the course of least resistance
For a deck that either comes warped or goes bananas
later just sitting in the box, I think it may relate to the
nature of wood (cardstock/paper) which has "memory"
because of the cell structure ~ sort of like conformity,
where it will often reform along certain "lines" naturally.
Shrink wrap (cellophane) can retard or exagerrate this,
but to allow the cards to flatten out all by themselves
you might try mixing them up so they are not the same
way when they are laying stored together and warping.
That was "Right" brain..."Left" brain says flex 'em all up!
