Great Blazing Flame Dragon (Custom Card designed as a generic card that works well with my Archetype)

Card text:
When your opponent declares a direct attack, you can Special Summon this card as a monster(Level 4, FIRE, Dragon-type, 500 ATK, 500 DEF). This card is NOT still treated as a Trap card. When this card is destroyed by battle or by your opponent's card effect, destroy all cards on the field. This effect cannot be negated.

Just you know, I did have to move this because you lack the required content needed for Advanced. (Did you at least read the announcement at the top of the section?)

 

Also you may wish to reload the card pic, so we know what type of Trap this is; assuming Normal.

[xlArisenRoselx]

Yes it is normal. I Dont know why it glitches like that.

The cardmaker's always had this problem; will need to get YCMaker to fix it, if he still cares about this site. 

 

But onto the card itself, I'm not fond of this card being an unchainable field nuke when it gets blown up (and backrow removal is very prevalent nowadays). Yeah, we got stuff like Black Rose that does the same thing, but remember; she's chainable (and you can negate it with a card effect). This one, you CANNOT. Get rid of the "cards cannot be activated" effect. The SS effect is fine.
