Hey guys i'm coming to you with a new card that i really like. I find it really good and I don't know anyone who plays it. I thought about typing about it because i'm making a crusher/gravekeeper deck for the new grave oriented format. heres what it does

Genex ally crusher
LV 4   a dark machine monster   ATT: 1000  DEF: 2000
EFF: once per turn, when a monster with the same attribute as this card is normal summoned to your side of the field, you can select one card on your opponents side of the field and destroy it.

Now i like using this card because with grave keepers you can flip a spy on your side and special summon a descendent or spy or what ever you want to get and destroy one card on your opponents side of the field. thats a plus one from you and a neg one for your opponent. I also like how back when i got the idea form youtube that tehere were not xyz monsters but now that should make this deck more powerful. get a descendent with spy blow up a card with crusher, tribute spy for descendant blow up another card and then xyz'd.
over all i really think this card is good and playable. not exactly broken but good.
