If you control no other cards and have at least 1 other card in your hand: Shuffle all Beast-Warrior-Type "Bujin" monsters from your Graveyard into the Deck (min. 1), and if you do, send your entire hand to the Graveyard (min. 1), then you can add up to 3 Beast-Warrior-Type "Bujin" monsters with different names from your Deck to your hand. You can only activate 1 "Bujinunity" per turn.
