Target creature gains deathtouch and lifelink until end of turn. Investigate. (Create a Clue token. It's an artifact with ", Sacrifice this artifact: Draw a card.")
Other creatures you control have haste.Whenever one or more face-down creatures you control deal combat damage to a player, draw a card.Whenever a face-down creature you control dies, return it to the battlefield face down under its owner's control if it's a permanent card, then turn it face up.
As an additional cost to cast this spell, you may collect evidence 6. (Exile cards with total mana value 6 or greater from your graveyard.)Each opponent sacrifices a creature of their choice. If evidence was collected, instead each opponent sacrifices a creature with the greatest power among creatures they control.
