Very strong deck, based on drawing a lot of card (thanks to either danger and synchro effs) and special summon monsters. The perfect combination between Danger and fabled effects gives the opportunity to special summon synchro monsters very easly, who help you to draw many cards.
Chawa and cerburrel , 1 and 2 stars, are very versatile in order to obtain all synchro you need.
halqfibrax is perfect to summon formula synchro in order to synchro fusion it with librarian and ragin to have Cosmic Blazar Dragon in chain to negate (and also we draw 2 cards)
This deck is not very simply to play, player has to make perfect choices each turn; but it can give you big satisfactions
