This card is treated as a Normal Monster while face-up on the field or in the Graveyard. While this card is a Normal Monster on the field, you can Normal Summon it to have it become an Effect Monster with this effect.● During your End Phase: You can target 1 Equip Spell Card in your Graveyard; add that target to your hand. You can only use this effect of "Knight Day Grepher" once per turn.
A very solid gemini monster. Fair stats and a very nice effect if you use multiple copies of [Supervise], potentially extracting all you need from the graveyard, which in turn returns gemini monsters as well.
A nice combo: [1 Knight] + [2 Supervise]. Die, return, equip, return 1st eq from grave, repeat.
(1 card alone wont be able to break the chain without an additional effect.)
