As Big E, pin or submit the New Day in a 1-on-2 Handicap Match on Legend difficulty.
Here is what I did:
1. Change the Settings
To make this easy, go to Gameplay Settings and set the Submission Mini-Game to Rapid. Then, adjust the Submission Mini-Game sliders:
Player Button Press Strength: 100
Player Wrong Press Penalty: 0
AI Button Press Strength: 0
AI Wrong Press Penalty: 100
2. Match Setup
Character: Big E.
Opponents: Xavier Woods and Kofi Kingston (New Day).
Difficulty: Legend.
Match Type: 1-on-2 Handicap Match (Standard, not Tornado).
Win Condition: Set to Submission Only.
3. During the Match
Stun the Partner: The biggest challenge is the tag partner jumping in to save the legal man. To stop this, knock the partner off the apron so they are stunned on the floor.
Apply the Hold: While the partner is down, immediately use a submission on the legal opponent.
The Win: With the settings you changed, the AI will tap out almost instantly. Once they submit, the achievement will pop.
