Iceland 2021 - Sentinels (NA team that people thought to be the best in the world)
Iceland 2022 - Optic (NA team that people thought to be the best in the world)
Berlin 2021 - Gambit (EMEA/CIS team that beat Optic/ENVY)
Copenhagen 2022 - FPX (EMEA/CIS team that beat Optic/ENVY)
Champions 2021 - Acend (EU team that underperformed in Berlin)
Champions 2022 - Fnatic (EU team that underperformed in Copenhagen)
Obviously this doesn't work if PRX wins which I would not have any problem with.
