Enchantment
Whenever one or more creatures you control deal combat damage to a player, investigate. (Create a Clue token. It's an artifact with "
, Sacrifice this artifact: Draw a card.")
, Exile a creature card from your graveyard: Investigate. You gain 2 life.
If you sacrifice a Clue for another card's cost or effect, such as that of Angelic Purge or Tamiyo's Journal, you can't also pay and sacrifice it to draw a card.
