When Bazaar of Wonders enters the battlefield, exile all graveyards. Whenever a player casts a spell, counter it if a card with the same name is in a graveyard or a nontoken permanent with the same name is on the battlefield.

Reveal a card in your hand, then put that card onto the battlefield if it has the same name as a permanent.

Return target nonland permanent and all other permanents with the same name as that permanent to their owners' hands.

As an additional cost to cast this spell, sacrifice a creature. Search your library for a card with the same name as target nontoken creature, put that card onto the battlefield, then shuffle.
