"Diffusion Wave-Motion" Rating Score by kyo

A spell that makes his Spellcasters of level 7 or higher attack all enemies. Also suppresses the effects of the opponent's monsters destroyed by battle.
Looking at the effect alone, it looks like it could be quite decisive, but it hurts that attacks other than the target monster are blocked. In terms of battles damage, it is stronger to equip a flashing twin sword Trice. Only monsters that have or have been given the resistance to "not be affected by Spell", such as Horus Black Fire Dragon Level 6, can escape this disadvantage. If you hit there, it might be a one-hit kill.
Although it is difficult to make use of it, it is actually a relatively blessed card for rulings. If the opponent's monster disappears from the field, it can attack directly, and after the direct attack, it can continuously attack monsters that have appeared on the opponent's field.
What the above means is that it is possible to hunt Goze and 《Tragoedia》at the same time as they appear, or that you can actively Special Summon monsters on the opponent's field to add damage.
Furthermore, it can be said that the fact that his spell-using trump card, 《Dark Magician of Chaos》, has returned to restriction is also a tailwind. After all, it can be said that Chaos Magician has the most suitable effect to make use of this card.
