|Effect||FLIP: Special Summon 1 "Gravekeeper's" monster with 1500 or less ATK from your Deck.|
Gravekeeper's Spy has to be my favourite Gravekeeper's card. When combined with necrovalley it has 2500 defense points along with being able to summon a descendant for free!! So it is basically one FREE card destroyed on your opponent's side of the field. Easy to get rid of that poxy Spirit Reaper or that Gravity Bind for example.
Spy can also be used in synchro summoning decks as it enables you to get a free monster which enables you to Synchro summon some of the bad boys like Stardust Dragon etc.
I use Gravekeeper's spy in my Gravekeeper's deck and to be honest; if you don't have 3 in a deck you are stupid!!
