Hiyas there, welcome back first and foremost!
The Assemble Team Power is bought from the Pay 2 Win vendor for what I think is 10 mill inf. These powers are permanent but have a moderate cool down. You also can buy from the P2W vendor summon team mates, Team mission teleport, base teleport, and self mission teleport powers. They all cost about between the range of 1 mil to 10 mil max but the powers are very helpful especially in Long TF/SFs like Dr Q where you need to travel long distances and other zones for quests! Enjoy!
