I put this guy in my Shiranui deck.
Send those zombie boys into graveyard, where they can activate their effects, and straight away sychro summons while clearing out opponents field.
Currently, I mix Mayakashi and Shiranui together. And this fella really help out big time.
First effect is pretty much a "revealing" Jar of Greed that have strict activation condition.
Even if you have 2 other Noble Arms face-up, the unpicked card will still be drawn in the next draw phase. Unless deck is shuffled by any means.
It's excellent because it doesn't care if they are on the graveyard or removed from play. This card and the WL field spell cover multiple situations your opponent can cause, making them so good for WLWC decks.
