Bernardo Faria is a 5x World Champion, but never trained any substantial stand up art. He's dabbled in both Judo and Wrestling, but never consistently. He shows his favorite takedown that can be effective even against an experienced wrestler or judoka.
This takedown emphasis the Art of War, attacking where the enemy is weak. Wrestlers are unfamiliar with Lapel grips. Therefore, use the lapel to set up your takedown. Likewise, the judoka is unfamiliar with leg attack so set up a sweep single.
