rare, 20 turns, for one hour, all battles and voodoo: players name shall be rendered invisible, "Player X" attacked you at Regis. Anywhere (port battles, etc). The "Player X" will revert back to the players actual name after 24 hours.

It will be obvious when you check the plunder page and the battle report. You can see what ships you've been attacked by.

well two options--first is to just make the card cover voodoo. Second, simply have a placeholder account that gets credited on all the various pages (the Player X option) for a day.

If the card covers voodoo, the card should make the next voodoo cast on a player automatically undercover, with the same specifications, rare, 18-20 turns.

Card covers voodoo is the most likely. Undercover plunders might give you away with fleet's name and ships types in battle report. Card covers voodoo.. Suitable for most cards except Chains of Justice

I like this idea, complete undercover voodoo would be amazing and would be interesting to see how that plays put.
