In a 2v2 game, if my partner's unit controls a battlefield at the start of my turn, and I flash their unit away and move my unit onto the battlefield, do I score conquest?

Ruling: No, you cannot score conquest on a battlefield that your teammate controlled during the beginning phase of your turn, even if you remove their unit and place yours during that turn.

Sequence:

• At beginning of turn, teammate's unit controls the battlefield
• You flash away teammate's unit
• You move your unit onto the battlefield
• You do not score conquest because your teammate held it during beginning phase

Nuances:

• Control is not shared between teammates in 2v2 formats
• The key factor is who controlled the battlefield during the beginning phase, not who controls it later in the turn
