It would be nice to make a storm which would change the atmosphere of a planet. I would like to surprise my enemy to change their oxygen planet into carbon dioxide and look them suffocate in one turn (when planet size for their race changes)
This could actually be succesfull with only one ships, if there is no fighters and/or ships around a planet and you would put your "storm ship" into "Don't get hurt" battle plan. First, get into corner in battle and stay there, then change the planet
