"Select 1 face-up Effect Monster on the field. Its effect(s) is negated and it cannot attack. If it is destroyed, destroy this card."

This card is so good this format. Although Veiler is a tuner and can be a surprise, this card is in my eyes a lot better.

Pros:
1) This card can be used OUTSIDE of the main phase, and on your turn, compared to Veiler's restrictions.
2) The Monster cannot attack, so allows for some battle phase shenangians
3) Can be used with Trunade/Scrap Dragon for combos.
4) Not many people realize this card still exists and often rush into this after I tell them I play 0 veiler

Cons:
1) A lot more counters to this card
2) MST/ Dust Tornado means you can force plays through against this.
3) Veiler is harder to negate
4) This card doesn't fuel Sorc/Avarice

Think about this card - it locks a card onto the field - all the power in this game sits in the yard and in the hand lately - it ties a card down where it is of little use anymore.

Fiendish Chain will have its day.
