Lore:

1 DARK Tuner + 1 or more non-tuner monsters
This card is also treated as Fiend-Type. When this card destroys a monster by battle and sends it to the graveyard, destroy all other monsters on the field (including this card), if this card was sent to the graveyard by its own effect Special Summon it to your side of the field in your next Standby Phase.

[ragnarok1945]

pretty good nuking effect, maybe on the OPed end though in terms of the recycling effect

I would have allowed it to return to the field during your next standby phase, but then have its effect negated for the next 2 turns or something like that

that way you can't just keep abusing the effect again and again

[Kirun Wolf]

It's a very strong field lock, even for a sync 10. I don't think it's horribly overpowered though.

[FateTheSeer]

I don't believe its overly OPed, just look at Volcanic Doomfire, which only nukes your opponents field and inflicts burn damage and then your other monsters can attack, with this dragon it nukes the whole field including itself so your opponent can then attack you directly, added to the fact that it can only revive itself if its destroyed by its own effect, so cards like Prime Material Dragon, Stardust Dragon and Destruction Jammer can easily bugger it up.
