Although there is plenty of Fiend-type monsters, they do not receive enough support cards to be made into a decent and versatile deck in the current card pool.
You will automatically be able to get your hands on a copy of Dark Necrofear. It is a very strong card with a strong ability that can change the flow of a game. The only drawback is that it should be used in a fiend deck to special summon it as early as possible.
Tether of Defeat
This is a very good skill due to the fact that you can choose whether you want to mill you or your opponent's deck. This skill is versatile as it can be used to mill your opponents deck to win or send cards into your graveyard for specific reasons, e.g. - Dark Necrofear, Shadow Ghoul, Desert Twister.
