This deck is used to quickly upgrade low mana beasts and quickly destroy your opponent. This deck uses high powered beast creatures with a small mana cost, and using cards like Advocate of the Beast to buff them up. It also has regeneration so the buffed up beasts don't die and lose all the tokens. Once the beasts are buffed up enough, the deck has Overrun to give all of them +3/+3 and trample, which should by then be plenty enough to destroy your opponent. Also, if a good card is put in a graveyard, the deck has reclaim to bring them back.
