There were some weird things about his team. I agree with your points; seems strange to even use EQ and hit his ally when he could have used Gyro Ball, or even better set up TR (I'm hoping that team was a TR team; it looks like one). He even tried to Crunch Scrafty! Though FB is understandable; it's the only way Reuniclus can take on Steel- and Dark-types. He had some smart play though, like switching in Gastrodon to absorb Water Spout.
Skill Swap is a greatly underrated move, though I've only seen it used well on Cress excluding gimmick teams. But as you said, it has multiple uses, especially with good teammates. I have fantasied of a Pokemon with Skill Swap and Contrary to pair with Overheat Chandelure, Draco Meteor Latios and Intimidate Close Combat Hitmontop. Complaints about unconventional tactics being stupid are not warranted if the tactics are good and are shown to work, especially if one loses to said tactics. That's how the metagame develops, with new tactics being used and shown to be viable. Often it's the unconventional tactics that win tournaments at the highest level of play.
