The Scum Cloaking Device is unreleased, so I'm not sure this should be here yet but i thought i would ask since i know its going to come up once the card is released.
The illicit cloaking device reads as
"At the end of each round, if you are cloaked, roll 1 attack die. On a focus result, discard this card, then decloak or discard your cloak token."
and Stygium Particle Accelerator reads as
"When you either decloak or perform a cloak action, you may perform a free evade action."
End Phase rules read as
During this phase, players remove all evade and focus tokens assigned to ships and return them to the action token supply. Target lock tokens and stress tokens remain in play until certain conditions are met (see pages 11 and 16).
Some card abilities or missions may instruct players to resolve certain effects during the End phase. If this is the case, do so at this time.
After completing the End phase, the round is over. If neither player has destroyed all of his opponent’s ships, a new round begins, starting with the Planning phase.
It seems from the end of Phase rules the order of events is
1. remove tokens
2. Do end of round effects
3. check to see if someone has won if not begin a new round.
So if your cloaking device gets removed at the end of the round and you have the Stygium Particle Accelerator does the evade action you took get removed or does it stay?
