We should probably come up with place holder names for the Ruler series, I guess…
RD/SBD3-JP030 魔将方円舞 Mashou Houenbu (Fiendish Commander Dance)
Normal Trap Card
[Requirement] When an Attack Position monster (Level 7 or higher/Warrior-Type) you control is destroyed by an opponent’s attack or the effect of an opponent’s Trap Card, you can activate this.
[Effect] Choose 1 “Yamiruler the Dark Delayer”, “Fiendish Commander Kimeruler” or “Fiendish Commander Semeruler” in your Graveyard, Special Summon it to your side of the field in face-up Defense Position.
Ark Commentary: If the merchandise name for Yamiruler stands, I guess “Dance of the Dark/Dark Dance” could work here.
