In celebration of the passing of the 13th Amendment to the Constitution of the United States, January 31st 1865, I have made this new card.
Sacrifice on the cost means that you must discard three (3) total cost, not three total cards. You can usually accomplish this by discarding one common specialty recourse which allows you to harvest three resources.
Sacrifice must be done on Harvest Phase.
If you forget to Sacrifice on Harvest Phase then you must wait until next turn and act according to the Turn Phase.
You will notice that Entice, Capture, Entrap, Ensnare and Enslave are all listed.
Some of the decks for sale use these terms.
Note: Egyptian Empire "Traps" card remains unaffected by this "Entrap" negation.
Enjoy your card!
Enjoy your freedom!
