Lifebringing Treasure Hunter

Whenever Lifebringing Treasure Searcher attacks,
you may search your library for an artifact, reveal
it and put it in your graveyard.
Whenever an artifact goes to the graveyard from
a library, each player reveals a land from their
hand. You and target player create a token copy
of target land in an opponent's hand.
Opponents can't tap land for colorless mana.
