I'm playing another only yugioh game where you can use anime only cards as well as OCG and TCG, it's not broken since most anime cards are still banned but it allows more archetypes but it is slight broken where you can get special items during events that allow you to use banned cards, but my main point is I need to prepare for a duel against someone who uses the Anime Version of Oricalcos,
Seal of Oricalcos
All monsters you control gain 500 ATK. This card cannot be destroyed or negated by card effects. Your Spell & Trap Card Zones are also treated as Monster Card Zones. Monsters in your Spell & Trap Card Zones cannot be selected as attack targets unless your original Monster Card Zones are unused. During your Main Phase, you can move monsters from your original Monster Card Zones to your unused Spell & Trap Card Zones, and vice-versa. Destroy all cards you control that list "The Eye of Timaeus", "The Claw of Hermos", or "The Fang of Critias" in their texts, and return any other cards listed in their card texts to the field. If a player loses the Duel, they lose their soul, and the winner can leave the seal.
So, my main problem is dealing with the extra 500atk points, doesn't seem big, but it soon becomes as annoying as dealing with a Gravekeeper deck...except you can't get rid of the field by any means, and your opponent can hide his monsters in the back row.
So any suggestion will help, think of anything, even anime only cards and banned cards, I also have one of the items I mentioned above.
