Tripple Boggey III

Whenever a creature you control dies, each opponent sacrifices a creature with the highest power or toughness.
At beginning of your upkeep, you may pay {3}{u}{b}. If you do, look at target opponents hand and choose a card. You may cast that spell without paying its mana cost.
"The price for disobedience is your life. The price for loyalty is one I care less, I win regardless."
