The idea is to use either 4-LOM or Leebo on a Large ship twice, and on the that second time you use it to have a ship nearby drop the EMP Device (Binayre Pirate or Ahsoka Tano would be ideal). The next turn, the large ship does suffer from the Ion Effect but then all four Ion Tokens would be removed from the ship setting you up for at least one more use without ill effect.
Thoughts?
