Because Kano Is Such A Good Sport (Orichalcos Cards) [WIP]

[Premier Alexander Romanov]

The idea behind these cards is corrupted, mutated versions of the monsters Summoned in the anime that were placed under the effect of the Seal of Orichalcos. If I got the effects right, they can count as Normal Monsters while on the field and in the Graveyard, but gain effects while still being treated as Normal Monsters while the Seal is on the field. They revolve around Normal Summoning like crazy, and overwhelming the opponent. However, they have 500 less ATK and DEF than their regular counterparts. Let's see if you can correctly guess all of them, though I have taken a few liberties, such as combining some cards together for the sake of convenience, removing cards that I simply couldn't envision a corrupted versions of (you can probably guess which card this is), and redoing the effects of Dartz's "pure" Orichalcos cards, save for Shunoros, and Malevolence, which you can find in the Single Cards.
Enjoy!

That is quite a lot of monsters then. XP

 

I like how some of them are really helpful, like the Orichalcos' personal Yamato, while others are more situational, but stally, like Keraino. 

 

I didnt quite read all of them, but I did get the idea and I enjoyed it a lot. And ermagherd Hivemother. Just that would make Orichalcos.dek a serious thing.

I'm glad you like this, because I haven't even gotten to the Xyz Monsters, or the Spells and Traps.
But yes, they are some of the weakest monsters in the game, but when you play the Seal, they become some of the most powerful.
Dragonlord and Hivemother would devastate modern decks.

Gremlin is funny. since it dosnt copy original, you're pretty much getting a constant 2000 boost (1000 base, +500 Seal + additional 500 seal from previous monster) plus whatver the monster had.

Should I modify it to be original ATK?
Also, the Corrupted rank-and-file are complete.
Now, for the Pures and the Xyzs.

[Premier Alexander Romanov]

Added the Pure Orichalcos monsters. They're much more powerful, and count as Normal Monsters to support Shunoros, but have the added restriction of not being able to be Special Summoned.
