Barter in Bark

Restore 4 (When this enchantment enters the battlefield, you may shuffle up to 4 cards from your graveyard into your library.)
At the beginning of your upkeep, return a card of an opponent's choice from your graveyard to
your hand. Then you may search your library for
a card with the same name as the chosen card and put it into your graveyard, then shuffle your library.
