Bujinunity

① If you control no other cards and have at least 1 other card in your hand:
Shuffle all Beast-Warrior "Bujin" monsters from your GY 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 "Bujin" monsters with different names from your Deck to your hand.
(You can only activate 1 "Bujinunity" per turn).
