Can you move two ganking units from one field to another at the same time?

Yes, you can move multiple units with Ganking from one battlefield to another simultaneously.

According to Rule 144.3 (and supported by RiftJudge FAQ 8465), players may perform multiple units' Standard Moves at the same time. While Ganking (Rule 810.1.b) provides the specific permission to move between battlefields, it is still a Standard Move.

How it works:

1. Declare the Move: You choose the destination battlefield.
2. Select Units: You select your multiple units at the origin battlefield that possess the Ganking keyword.
3. Pay Costs: You exhaust all units involved in the move simultaneously (Rule 144.3.c).
4. Arrival: All selected units arrive at the destination at the same time.

Important Considerations:

• No Chain: Because this is a Standard Move, it does not use the chain and must be performed during your Main Phase when the state is open (Rule 144.1.b). You cannot use [REACTION] cards during this move because no chain is created.
• Control: Ensure you have control of the destination battlefield; you cannot move units to a battlefield that already contains units from two other players (Rule 144.4.a.1).
• Emptying a Field: If moving these units causes your original battlefield to become empty, you will lose control of it (as per RiftJudge FAQ 8334).
