Gate of Infinity
(Rule)Description: If your Army Faction is **^^Grey Knights^^**, at the end of your opponent’s Fight phase, you can select a number of units from your army that are on the battlefield (excluding units that are within Engagement Range of one or more enemy units), providing every model in those units has this ability. The maximum number of units you can select depends on the battle size, as follows:
Incursion - Up to 2 units

Onslaught - Up to 4 units
Once you have made your selections, remove those units from the battlefield and place them into Strategic Reserves.
