Oogie Boogie's Lair

Each opponent loses 1 life for each creature you control.
" 'Cause I'm a gamblin' Boogie Man / Although I don't play fair / It's much more fun, I must confess / When lives are on the line / Not mine, of course, but yours, old boy / Now that'd be just fine" - Oogie Boogie (the Nightmare Before Chistmas - 1993)
