AD&D Monster Cards Campaign

Because it's something I always did want (in fact, I hand-made some of my own back in the day), and thanks to some recent suggestions by commentators here, I picked up a full copy of the old AD&D Monster Cards product off E-Bay the other week. Just for a moment (since it's something we are wont to do), let's imagine running a campaign where the only monsters are those you can show to the players on these cards (organized OD&D-style by category and increasing Hit Dice):

• Humanoids -- Kobold, Goblin, Gnoll, Lizard Man, Troglodyte, Bugbear.
• Giants -- Hill Giant, Stone Giant, Frost Giant, Ettin.
• Undead -- Ghoul, Mummy, Spectre, Vampire.
• Dragons -- Black, Red, Silver, Gold.
• Lycanthropes -- Werewolf, Weretiger, Seawolf.
• Fey -- Dwarf, Elf, Halfling, Centaur, Hybsil, Wemic, Sylph, Satyr, Korred, Treant.
• Flyers -- Hippogriff, Peryton, Androsphinx.
• Outsiders -- Wind Walker, Salamander, Efreeti, Succubus, Demon Type V, Barbed Devil, Nycadaemon.
• Animals -- Axe Beak, Giant Weasel, Dire Wolf, Jaguar, Carnivorous Ape, Giant Constrictor Snake, Sabretooth Tiger, Triceratops, Tyrannosaurus Rex.
• Insects -- Bombardier Beetle, Ankheg, Giant Scorpion, Thri-Kreen.
• Chimerical -- Grippli, Blink Dog, Zorbo, Su-Monster, Displacer Beast, Leucrotta, Gorgon, Galeb Duhr, Stone Golem.
  
• Aberrations -- Obliviax, Carrion Crawler, Land Urchin, Gelatinous Cube, Rust Monster, Mihstu, Umber Hulk, Will-O-Wisp, Tunnel Worm, Neo-Otyugh, Roper, Giant Slug.
  
• Aquatic -- Ixitxachitl, Merman, Locathah, Sahuagin, Hippocampus.

I kind of like it; there's a nice mix of old/mythological "standbys" and more exotic/unique-to-D&D-play creatures. While there are some surprising things left out (no Orcs, Ogres, or Trolls, for example), I do like how many of the categories meet the "Magic Number Seven" rule, giving some nice texture while remaining manageable for the DM in world-building and play.
