This is what I've read from the small text so far...
Hieratic Seal of the Dragon King (Light attribute)
6 Star Dragon/Gemini monster
This card is treated as a normal monster while faceup on the field or in the graveyard. While this card is faceup on the field, you can normal summon it to have it become an effect monster with this effect
- You can tribute this card; Special Summon 1 "Hieratic" monster, except "Hieratic Seal of the Dragon King", from your Hand, Deck, or Graveyard in face-up Defense Position.
Seems... pretty bad, doesn't really bring much to the plate for Hieratics. And it'll eat up a normal summon for its effects. Supervise is too much of a hand constraint (and too few targets, really) to run it in this deck. Hell, with only one week of actually building and playing Hieratics on Dueling Network, hand problems are KILLING me inside. Gozen Match is helping a little in non-turbo builds, but I just can't seem to keep up with meta.
Say, why doesn't someone change the thread name to Hieratics? It's the official TCG name after all. :P
