Effect Veiler

Effect Veiler
During your opponent's Main Phase, you can send this card from your hand to the Graveyard to select 1 face-up Effect Monster your opponent controls. Negate the effect(s) of that monster until the End Phase.

This card is very useful in this format due to the countless incidents of play ability. You can literally use it on anything your opponent throws at you whether its against Agent Deck's, or Samurai Deck's this is a must for any competitive player. Its also a level 1 tuner to help synchro those awesome cards in your Extra Deck. As well as being a Light target for Black Luster Soldier- Envoy of the Beginning.

This card comes in 3 Rarities: Ultimate Rare, Ultra Rare and just normal Rare. There is a lot of value if your think about obtaining one of these due to sheer usefulness and if you go Ultimate then prettiness as well. I feel every duelist should either main this or side, it is a must have.
