Pairings at team events like the ETC is a whole sub-game in itself and something that captains and players can spend a great deal of time and effort on. I'm not sure how other events work, but at the ETC each country's lists are published before the event, which allows teams to run the numbers and consider possible match-ups.
Erle over at Hive Fleet Hyenna has put together an interesting series of posts going into his theories as Team Belarus' Captain. If you're interested in this sort of thing or perhaps looking to spy on an opposing team, I recommend taking a look!
If this all seems like far too much effort, there's always Team Iceland vs Team Belgium's highly tactical method... Enjoy!
