Saim-Hann Seer reads: "Choose an enemy unit at this planet. That unit loses all printed keywords until the end of the round. Then, this unit gains all keywords lost as a result of this effect until the end of the round. (Limit once per round).
Gun Drones reads: "You may deploy this card as a drone attachment with the text, "attach to a non-vehicle army unit. Attached unit gains Area Effect (2)."
If Gun Drones is attached to an army unit, giving that unit Area Affect (2), can Saim-Hann Seer use it's action to steal the area affect keyword?
