Am I reading these rulings correctly? Is it true that, even though Levia-Dragon - Daedalus, and Demise, King of Armageddon, have very similar ignition effects, that, if flipped face down, one of them will stay, while one will die? I can't help but wonder what the obscure rationale is behind this.
Levia Dragon - Daedalus:
"¢ When "Book of Moon" is chained to "Levia-Dragon Daedalus"' effect to flip it face-down, the effect still resolves, but "Levia-Dragon Daedalus" is destroyed by its own effect, since it's no longer "this card", it's just "a card".
Demise, King of Armageddon:
"¢ If an effect is chained to "Demise's" effect to flip "Demise, King of Armageddon" face-down, he is still not destroyed by his effect.
Levia Dragon - Daedalus:
