Graveyard Chess

From BoardGameGeek:

Graveyard Chess is an undead-themed chess variant in which the Kings are replaced with Necromancers, and the other pieces are replaced with various undead creatures. Functionally, Graveyard Chess plays similarly to regular chess, but with a smaller board, and a simplified lineup of pieces. The main key difference is that after you capture an opponent's piece, you can skip your turn to resurrect it onto the board as your own. -description from the designer
