Obsessive Pursuit 
Enchantment · Rare · Avatar: The Last Airbender · #112
When this enchantment enters and at the beginning of your upkeep, you lose 1 life and create a Clue token. (It's an artifact with "{2}, Sacrifice this token: Draw a card.")
Whenever you attack, put X +1/+1 counters on target attacking creature, where X is the number of permanents you've sacrificed this turn. If X is three or more, that creature gains lifelink until end of turn.

- 2 October 2025Clue tokens are artifact tokens with "{2}, Sacrifice this token: Draw a card."
- 2 October 2025Creating a Clue token this way isn't the same thing as investigating. Notably, an ability that triggers whenever you investigate won't trigger because of creating a Clue token this way.
