Rulings:

• 7/13/2018 The sacrificed creature’s last known existence on the battlefield is checked to determine its power.
• 7/13/2018 You must sacrifice exactly one creature to cast Thud; you can’t cast it without sacrificing a creature, and you can’t sacrifice additional creatures.
• 7/13/2018 Players can respond only once Thud has been cast and all its costs have been paid. No one can try to destroy the creature you sacrificed to prevent you from casting this spell.
