So I am guessing this idea is going to be extremely controversial, and have many different perspectives. So lets dive in.
This is a simple card, with a lot of specific rules in terms of use.
The Ultimate Sacrifice: Give up all your wealth, turns, and voodoo, leave your nation, and have 1/4th of your ships removed in order to destroy one enemy fleet.
Rules of Voodoo Part 1: 100% pierce, not anonymous, CAN ONLY BE USED ONCE, Cannot be casted on self.
Rules of Voodoo Part 2: Only affects docked fleets, Only affects fleets with higher than 100 danger, all bank accounts or turns invested in treasure hunting are cleared. There is NO way to hide turns or gold, all trace is cleared. Castor MUST have at least 100million gold present and 200 turns at time of usual. The Castor CANNOT receive loans or donations for the next 5 days. Lose 1/4 of ships, completely of your choice.
Warning: NOT EVERYTHING will be lost, materials will still be in the warehouse, so you can always sell a ton of tools after usual and get millions back.
Crafting: Since this card destroys all your voodoo, it is obvious that you will need a lot of voodoo to create this card (and why keep it limited? You will lose all your voodoo after usual regardless). Craft = 2 hideouts + 100 buried treasure + 5 fire ships + 1 mindbar + 5 Call Leviathan + 200 drums of war
This card is pretty much a last breath for players under serious stress that are not complete newbies. Would be used by players in a desperate attempt to injure an attacker. I would expect the use of this card to have serious retaliation, so use should be used in a war struggle.
