The Great Seal of Orichalcos (retrain)

The Great Seal of Orichalcos
[Field Spell]
All monsters you control gain 500 ATK/DEF.
This card is unaffected by your opponent's effects while you have a monster (even if only in the Spell & Trap Zone).
If you could Summon/Set a monster(s), you can place them in your Spell & Trap Zone(s) as Spells instead.
If your opponent would attack directly while you have no monsters in your Monster Zones but have monsters in your Spell & Trap Zones, they must instead select 1 of them to attack.
Monsters treated as Spells this way can still use their effects.
During your Main Phase, each monster treated as a Spell this way can once per turn move to the Monster Zone until the end of the turn (you can swap it with a monster in your Monster Zone during that time).

Soooo ummmm... 6 effects in order to mimic the anime Orichalcos as much as possible. The "Once per Duel" the "no Extra Deck", and "OPT not destoryed" bits are arbitrary conditions placed by the IRL version's designers. The fact the Legendary Knights affect them is something IDK how to bypass and translate. The Spells are not specified as Continuous/Equip/etc. because I don't want them to specifically be exploited by support for those. Pendulums also were their own Spell branch that just stayed up so I'm taking this liberty.

I've seen a version of it that makes the monsters DARK which would make sense given the corruption plot it was in, but I don't think it was explicitly stated in the anime ever....... or that it played a particular role if it did. 

This is my compromise with the IRL game developers stating that they can never break the design choice of "S/T Zone will always has S/T and Monster Zone will always have monsters" which made OG Orichalcos unfathomable to them and made Spirit Message (FINAL) cards into unaffected 0/0 monsters under Dark Sanctuary. 

The way it works if would ever be removed by some ungodly way while monsters are in the backrow... they wouldn't go away but they'd be stuck in the back I suppose......

The monsters in the back row can be dealt with by Mystical Space Typhoon & Cosmic Cyclone?

The way it is currently written, yes. 
I am sorta leaning on the current game not focusing a ton on backrow removal and the old classic game having more limited forms of removal. At least until I figure that one out in text form to add.

Oh and my brother confirmed me that the anime seal DID make things DARK so I guess that's another edit underway.
