Random Blind Packs as SWAG.

My suggestion would be a variety of items, all of course cool items, randomly and assorted blindly as SWAG so that collectors could trade, collect and be excited at their own random selection.

Rough Example, in your packaging, 2 random items from the following list.

#1: Rune Stones (Injection Molded Plastic/Painted)
#2: One of three types of coins with LB's Face of course! (Gold, Silver, Copper)
#3: Silver Serpent pendant
#4: Gypsy Scarf printed in the theme of the game world.
#5: Famous Character Mini-Figure, (Mono-Colored but detailed like the old MUSCLE or MIMP figures from the 80s)
*#6: Super Rare Autographed Litho by the team (Really want one of these!)
