Unfortunately, his clever usage of Palpatine and Ion Projector doesn't actually work as described to keep a small base ship trapped until it's dead. It's a waste to use Palpatine on the second bump that triggers Ion Projector since that token will be removed after the victim completes his compulsory one forward.
You sure about that? Pretty sure that Ion Projector's token is dealt after the Ion Tokens are removed...
My bad, this one is going to come down to initiative. If the player with the Ion Projectors has initiative, it doesn't work. If they don't have initiative the trick works.
The timing on Ion Projectors and Removing an Ion Token both happens after executing a maneuver.
