Staff of Purging Light

Spell/Normal

Can only be activated during the Main Phase 1. After this card's activation, it remains on the field, but you must destroy it during the End Phase of your opponent's 3rd turn. When this card is activated: Reveal all Set Spell/Traps on the field, then, return it face-down. While this card is face-up on the field, if a card is Set to the field, immediately banish it after it is Set, also monsters you control cannot declare an attack.

its pretty violent card against deck that like face-down card. simple and quite effective for its niche

Hard to tell what the best use is actually. If a deck already does setting, it just reveals the ones already present, but prevents new sets from entering the field and especially hurts the ones that flip up and down every turn. If a deck doesnt set too often, the you have free real estate for a combo with swords of concealing light to just banish any non links.

That part is honestly a lot of fun. Though the "opponent can't set" plus brionac and dewloren making it infinite makes me wonder how debastating this Dark Simorgh in spell form would be nowadays.
