The card that transends history. Arguably the most expensive card in the world, although, no one would ever know, theres never been one for sale.
I'll start at the begining, there are 5 levels of yugioh tournament judge. u can get level 1 judge from attending any regional tournament, just ask the judge for a judge test.
Level 2 judge, the test can only be found in national tournaments and you have to be a level 1 judge already.
Level 3 can only be got at a national event when you have head judged a certain amount of tournaments (I think its 20, maybe 30) It is both a written and oral exam.
Level 4 there is no test, its awarded to you based on how well known you are, this means attending and judging massive tournaments like euros or even worlds.
Level 5 is pretty much an interview to work for konami, upon becoming a level 5 judge konami will offer you a full time job to work as a member of there staff, there are very very few level 5 judges in the world.
You have to be a level 5 judge (or a very high level, I think Ray Fong might have one since hes the head of the UK for yugioh) to get a seal of orichalcos. Also, as a level 5 judge there are annual meetings (I think its 2 or 3 a year) where you have to go somewhere to meet up with all the highest members of the yugioh staff for konami. This is where ban lists are discussed as well as many other things such as prizes, tournaments, prize support, shojen jump championship cards, promo cards etc etc etc. These meetings are mandatory and you must show your seal of orichalcos card or you will be fired.
I think you can all understand now why this card is so expensive. ^^ Lastly we need to go over spell speeds, just for those who don't know:
Spell speed 1: The slowest, this is normal spells or cont spells, say smashing ground, swords of revealing light etc.
Spell speed 2: Quick play spells, Normal traps and Cont traps. All of these cards can be chained to a spell speed 1 or 2.
Spell speed 3: Counter traps. Such as solemn judgement. Once a counter trap has been activated you can only chain to it with simular counter traps, this is why you can't chain "royal decree" to "pulling the rug".
Finally, Spell speed 4: The definition of spell speed 4 is strange. It is a card which can be activated from your hand, during your opponents turn. There are very few of these in the game, infact there is only kuribo, gravekeepers watcher, hearld of green light, hearld of purple light and D.D crow, all monster cards. However there is one spell speed 4 spell, seal of orichalcos.
Now, heres the real effect of the IRL Seal of orichalcos.
Seal of Orichalcos
Spell card: Spell speed 4 (the symbol looks like quickplay icon, but a little cooler)
Effect: Negate the effect of a spell or trap or the summoning of a monster and destroy that card.
Also, if you happen to get to play one of these judges there is also a sort of, hidden effect of playing against this card. If you win against a deck playing this card, the judge will give you 1 free pack of cards from the latest booster set. If you lose against a deck playing this card, you will have your photograph taken and your name, picture and ude number will be placed on the hall of shame.
