"Archfiend's Staff of Despair" Rating Score by ねこーら

Comprehensive evaluation: By using the strengthening effect together, it can lead to a significant weakening, or if you have the ability to attack the whole area, you can aim for a one-turn kill.
Since it's his ATK that's referenced, if you give him a strengthening effect, the range of reduction will be even wider.
If you equip it on a monster that can attack twice or attack all monsters, you can expect to do a lot of damage.
If you have an enhanced ability that can attack all monsters, it's only about Raidraptor - Rise Falcon.
If it's Ultimate Conductor Tyranno with a high ATK, can it really hit 5250?
Since it can be collected even after leaving the field, it can be used again without harming it by equipping it to a monster that cannot attack and using its weakening effect to use it as a material for another monster.
After that, because it is "Archfiend", it can be destroyed by satisfying the Special Summon condition of "Archfiend Commander", and the consumption can be completed with 1000 LP cost.
In addition, it also works reasonably well with Maha Vailo, Light of the Heavens in the same pack, and can be equipped and strengthened over there to weaken it, or hit it to double the damage.
Is it similar to the old 《Maha Vailo》+ 《Axe of Despair》move?
Also, if you equip ✪ Dark Chimera or Barox and use it, the weakening value will be quite complicated, so it's better not to do it.
