Great write-up. Looks like a good bit of stocks were assigned this week. For the number of trades probably not that many.
I have been playing Splinterlands game and I agree it is a timesink.
Here is the link to a webpage which calculates the value of card packs.
https://www.splintercards.com/tool-packvalue.html?ed=7&qty=100&cost=4.00&pot=0&guild=0
Keeping in mind that a basic pack is worth only 1.16.
Estimated value of a basic pack (4 commons & 1 rare, regular foil) $: 1.166
So unless you are investing in 100's to 1000's of packs there is a good chance you are losing value on each pack. Card rentals are probably a little better than playing the game. It still takes a good bit of management with each 3 DEC rental being worth 1 penny. I find writing a covered call for $20.00 profit much easier than getting $20.00 from managing the listing of 100's of cards.
