This is the culmination of the innermost teachings!
RD/MAX2-JP031 幻刃奥義－突陥攻事 Genba Ougi – Tokkan Kouji (Mythic Sword Mystery – High Speed Demolition/Mythic Sword Secret (Technique) – High Speed Demolition)
Normal Spell Card
[Effect] All face-up Normal Monsters (Level 7 or higher/Wyrm-Type) you control gain 600 ATK this turn. Also, all face-up monsters (3000 ATK or higher) your opponent controls lose 1200 ATK until the end of the turn.
Note: This card’s name is a play on 突貫工事, the term for high speed/rapid construction in Japan. Basically the 陥攻 completely inverts the name.
奥義 (Ougi) is a more complicated term, in that it likely means special technique, it should be noted for readers, 奥義 tends to refer to the innermost secrets of a religion, martial arts, occupations, scholarship, et al., the sort of things not taught to outsiders and are kept for only the most loyal and proven initiates.
Basically, Asana and Tiger’s new cards are special techniques meant for the most proven masters of both their styles.
