Ruination of the Past

[Lunar Origins]

 

Cannot be Normal Summoned/Set.  You can Set this card in your Spell/Trap zone (it is treated as a Trap card).  When this card is destroyed while treated as a Trap card:  Special Summon it.  Once per duel, if this card is Special Summoned by its own effect:  You can send all monsters on the field to the Graveyard, except this card.

Cannot be Normal Summoned/Set.  You can Set this card in from your hand to your Spell/Trap Zone (it is treated as a Trap card).  When this Set card in your Spell/Trap Zone is destroyed and sent to the Graveyard while treated as a Trap card:  Special Summon this card from your Graveyard it.  Once per duel, If this card is Special Summoned this way by its own effect:  You can send all monsters on the field to the Graveyard, except this card. Both players can only use this effect of "Ruination of the Past" once per Duel.

So, you can intentionally destroy this card with, say, Double Cyclone, to create a surprise (though once-per-Duel) nigh-unstoppable boardwipe?

I could see some shenanigans with this and Artifacts, as its effect would clear your S/T zone and sp. summon them all.  Its like a much more powerful Malevolent Catastrophe.  I would nerf it just a bit to help prevent this, for example destroying all face-up cards, or only monsters.

Ignore my last post, i missread the card
