Prophesied Blast

[Gorlois 11]

Normal Trap
Target 1 face-up monster on the field; while that target remains face-up, your opponent's Deck is turned upside-down. A monster Tribute or Ritual Summoned by Tributing the targeted monster, or Special Summoned from the Extra Deck using the targeted monster as material, gains the following effect.
• At the start of the Battle Phase: Destroy this card, and if you do, you take damage equal to its ATK on the field.

I am curious... Flavor wise, is this related to one of Ishizu_Ishtar cards: Blast_Held_by_a_Tribute. It seems to pay homage to her "prophetic" powers and the fact that she tried to use that card against Kaiba.

Anyways, I like the built in "Convulsion of Nature" effect as it gives you knowledge of what to expect. Last effect is nifty as it can put your opponent in a stand still for their Link monsters that used what ever you targeted, and it can kill your opponent or prevent them from battling in the event that they summoned something that has ATK over there current LP.

I fail to see connection between the deck-flipping effect and the disruptive one. Anyway, card is funny but not that great, IMO. As a Trap it is 1 turn slow, then it's opponent-dependent, plus you can't chain this card to a Tribute, Link, Xyz or Synchro Summon so you would have to activate this Trap preemptively, giving the opponent the chance to change its plays or respond to it. Not to mention that even if a monster were to gain the self-destructive effect, it applies in the BP so the opponent can attempt to get out out of the board before entering the BP. In short, the card has too many things going against it, and seems like a casual card at best. You can improve it of course. An idea that comes to mind is applying the self-destruction effect right away or on-Summon, so you can at least punish the opponent when it's using a monster on board as material for a Ritual or Fusion Summon.
