Did they have that really shiny laminated gloss to them, and would bend because the card backing was so flimsy it couldn't hold up against the contraction it caused?

Same. Did you ever get some with a raised, sandy texture and a gold trim? Those where weird.

Tons, of various quality. Some were just bad scans of real cards, printed onto poor quality cardboard stock. Others where weird amalgamations, as if someone had described the cards over the telephone. The "best" where always the interpretations of a single-card Exodia or alternate-artwork Egyptian Gods, all with bad translations.
