To me, a 131-card set does not provide the greatest value for future resale since you're talking about one-complete set and an extra half-complete set. With a 131-card master set, you'd only be 37 cards short on another complete OS2 set. So why not just get two full-complete 84-card sets? That's exactly what I've done. The 1st version I put together is the 84 card matte back variation set containing only Messy Tessie puzzlebacks and the Schizo Fran variation. I'm not sure if the Patty Putty/ Muggin' Megan back variations exist in matte, so there could potentially be 86 cards in the matte back set. Here's how I put together versions 2 and 3 of this set.
Both Checklist Variations for #46a, #46b, #47a, #47b indicating either Schizo Fran or Fran Fran for #49b.
Both award variations for #42a and #42b with either the Spaz Award or the Sneak Award on the back.
