Impulsive Pilferer

When this creature dies, create a Treasure token. (It's an artifact with "T, Sacrifice this token: Add one mana of any color.") Encore 3R (3R, Exile this card from your graveyard: For each opponent, create a token copy that attacks that opponent this turn if able. They gain haste. Sacrifice them at the beginning of the next end step. Activate only as a sorcery.)
