Wydar Sarkal Deck

Originally going though the set 4 spoilers Dullahan stood out as a really broken card sadly there aren't that many monsters that have more then 2 critical in the set to take real advantage. Still don't let that fool you this card is still crazy strong by combining the gorgon sisters and monsters with penetrate to get off explosive amounts of damage in one turn.

As aggressive as this builds looks its actually a lot more controlling so try to focus more on clearing your opponents field rather then all out attacking this will also give you an opening to use Decree of Dullahan to end the game.
