robin hood:
uncommon, 3 turns to cast. effect: a deserted voodoo card becomes yours.
so how it works? it chooses any existing card randomly, with equal chance for all cards. then it takes 1 of these cards from player who has most of the said card. do note it targets one with largest amount of that card, not player with largest voodoo chest. the target will get event notification, that robin hood has taken card x, but the casters voodoo log will not show who the card was taken from, it will only show what card was obtained.
alternative for the mechanic above would be to have it work exactly like tidal wave, and target top 10? largest voodoo chests, but that would likely be too easy way to drain useful voodoo from few selected people, and some of those gigantic chests might miss several voodoo cards that are useful.
bottom line is, that those who have most of anything do have too much, and they should share some of that. the more ships you have, the greater your risk grows, i really hope this would have similar effect on voodoo, and balance things a bit, and perhaps increase market activity aswell.
additionally i would like tidal wave to be added back to voodoo packs, as it is currently a gift only card, and it has become more rare than uncommon. i hope it was not removed due to complains from people that were its main targets, those people can afford, and should share some of their assets
