Zekrom is one of the best stall (and balance) breakers in the meta right now, especially with the rise of Toxapex on stall teams. However, Groundceus does a good job dealing with it so Gothitelle is used to trap and kill it. Zekrom gets a free Toxic on turn 2 when Mega Sableye switches out into Groundceus, you can then proceed to switch in Gothitelle and stall it to death with a combination of Calm Minded Psyshocks and Toxic chip damage. After Groundceus is dead, Zekrom can feel free to Hone Claws up and break the rest of the team. Lugia and Toxapex are OHKOd by a +1 Bolt Strike and everything else is OHKOd by a +1 Devastating Drake.
