[2x2 Tournament] Resurrection

All known bugs should be added to the rules, and it should be stated whether they can be used or not, so that everyone knows.

It won't work to simply address the Berserker bug; the wording will either be long and complex, or incomplete and ambiguous, leading to disputes.
The only simple solution is to ban the Berserker altogether. It will be very frustrating to see a Berserker with water walking after building the 4th level of the Guardian Maze.
