Found a bit of a cheeky way to do this without too many tools 🙂
Nice one @PhilipMannering
This might be one of my favorites in a while - an Iterative Macro AND I got to use my favorite Make Columns tool???? That's a tournament winner for sure!!
To create this algorithm in Alteryx iterative macro form, it really came down to a re-ordering technique that would not only "wrap" the players around for matchups (left to right on the top row, right to left on the bottom) but would also replace player two with the last player in the lineup with every round. Key players in this matchup were RecordID, Sample tool, and MY FAVORITE DARK HORSE TOOL EVER, the glorious Make Columns tool. I love this little guy... it's not often I find uses for him, but when I do, THEY ARE MAGICAL.
