a. 3 Equipment cards: a piece of yarn, a lump of coal, a burned out torch
b. 1 Ultra Rare Magic Card (artifact): Mordenkainen's Day Old Underwear
All kidding aside, there might actually be something to be said for this sort of division of playtesting labour (toned down a little from what's in the article, of course!).
At first I was like "Are you kidding me? Who would not read this thread?" And then, before I finished second sentence in my head, I was like "oh, right, freaking 1st of April, hate that date".
The sad/great thing is, the OP got me more excited about "Ranger Wickett Edition" than anything I've read from WotC so far. I really really dig the stunt system. Seriously, if he wrote that up and sold it as PDF I'd dump it in my 13th Age playtest rules and I won't need 5E.
