Creature â Human Warrior
Whenever Briarbridge Patrol deals damage to one or more creatures, investigate. (Create a colorless Clue artifact token with " , Sacrifice this artifact: Draw a card.")
At the beginning of each end step, if you sacrificed three or more Clues this turn, you may put a creature card from your hand onto the battlefield.
The tokens are normal artifacts. For example, they can be sacrificed to cast Angelic Purge or targeted by Root Out.
The token is named Clue and has the artifact subtype Clue. Clue isnâ€™t a creature type.
If you sacrifice a Clue for another cardâ€™s cost or effect, such as that of Angelic Purge or Tamiyoâ€™s Journal, you canâ€™t also pay and sacrifice it to draw a card.
Briarbridge Patrolâ€™s second ability looks at the entire turn, even if Briarbridge Patrol wasnâ€™t on the battlefield for some of the turn. It will see Clues sacrificed for any reason, not just Clues sacrificed to their own ability.
Briarbridge Patrolâ€™s first ability will only trigger once per combat damage step, regardless of how many creatures it deals damage to.
