Ghostrick Mary is part of the new ghostrick support being released in legacy of the valiant.

http://yugioh.wikia.com/wiki/Ghostrick_Mary

Effect: Cannot be Normal Summoned unless you control a "Ghostrick" monster (but can be Normal Set). Once per turn: You can change this card to face-down Defense Position. When you take damage: You can discard this card; Special Summon 1 "Ghostrick" monster from your Deck in face-down Defense Position. You can only use this effect of "Ghostrick Mary" once per turn.

This card is so amazing, first off all you have to do is discard it when you take damadge, effect or battle, and you get any ghostrick from your deck.
(not to mention the awesome artwork)

Person i think this is exactly what ghostricks need to become top tier.  Hopefully we can see some more support coming out with it.

Let me know what you guys think of the card and what tier you expect ghostricks to be (if any)

This card will do nothing as for Ghostrick's tier rank. Nothing.

ghostricks are good enough but yeah, kinda decent card. Will definetly replace the fake-fader.
