The Seal of Orichalcos

This card, its activation and effects are unaffected and cannot be negated by by all Card Effects except by the effects of Legend of Heart, Orichalcos Deuteros and Orichalcos Tritos. When this card is activated, destroy all cards you control that list "The Eye of Timaeus"/"The Fang of Critias"/"The Claw of Hermos" in their card texts and Special Summon any monsters from your Graveyard whose name(s) is included in the destroyed card(s)'s texts. Your opponent cannot activate Field Spell cards. Monsters you control gain 500 ATK and are also treated as DARK monsters in addition to their original Attribute. 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 unoccupied. During your Main Phase, you may move monsters from your original Monster Card Zones (or switch them them with monsters) in your Spell & Trap Card Zones and vica-versa. If this card's effects are negated, move as many Monster Cards from your Spell & Trap Card Zones as possible into your Monster Card Zones, then destroy all monsters in your Spell & Trap Card Zones.
