3-man deck check technique
Hello, I'm team-leading for the first time on Saturday at an SCG Regionals, and I have a 3 man deck-check team (including myself). I know I've seen a 3-man, rotating deck-check technique at Opens and GPs- it was something like 2 people swooped, one person pulled decklists, then one of them went back out to swoop for an early midround while the first 2 did the check? Am I remembering that right?
Basically, I'm just looking for information about that technique, and any tips with it (as well as advice about whether it would be a good way to run deck checks for a 150-300 player regionals event).
Any information will be appreciated :)
