Effect: Discard 1 card from your hand and declare 1 type of monster to destroy all face-up monsters of the declared Type on both sides of the field.

So what this card does is you discard one card from your hand call the type of monster light dark or something and it is destroyed. All monster on the field with that type are destroyed even yours.

Well this was one of the most anticipated cards in the wholes set I mean come on it can destroy a theme deck with all a certain attribute. So lets say you are facing an opponent with all dark monster. As soon as you get one of these guys out on the field you will seriously have a major advantage over them and there deck. This is going to be a deck staple and will be restricted to one like Japan. I think this is the reason sinister serpent is restricted here and in Japan. Well this is highly unlikely you will face a deck like that at a tourney but if you do remember what I said.

Well this is mainly for killing the usual cards everyone hates to go against and loves to have.  These cards like jinzo and all the rest. But really even after all the advantages if you are up against a yata deck using this card is not a good ides unless you run it with a sinister serpent and one other bad thing is the card has to be face up.

I love this card I just make sure I use it with sinister serpent because I do not like to get rid of my hand I give it a 4/5 in all formats
