UPDATE (changed Leaf): Using Lyra instead doesn't count as a retreat (like Revavroom) Set up Tinkaton with Orthworm, then you can use Gigaton Hammer multiple turns in a row by switching Tinkaton in and out of the active spot by using a combination of : - Retreat with Big Air Balloon, or by having 5+ energy on Tinkaton - Use Revavroom ability or Lyra to switch again - Use Lyra or Vroom first then retreat with another Pokemon with enough energy Lyra can also put Orthworm out of the active spot.
