Backfire - OTK! by GrandMasterFox

I know the odds of pulling this off are not that great, but it will net you victory and it only requires 3 cards to work.

1)Activate DNA Transplant and call out FIRE
2)Activate Backfire
3)Summon Nova Summoner

Now all that is left is to suicide enough monsters so that each one inflict 500 points of damage to the opponent when it is destroyed and each one replaces itself in the following manner:

Nova Summoner -> Nova Summoner -> Nova Summoner ->Shinning Angel -> Shinning Angel ->
Shinning Angel ->Uforoid -> Uforoid -> Uforoid -> Ufo Turtle -> Ufo Turtle ->
Ufo Turtle -> Masked Dragon -> Masked Dragon ->
Masked Dragon -> Troop Dragon -> Troop Dragon -> Troop Dragon.
You've lost 18 monsters in battle so thanks to backfire that's 9000 points of damage.

Just remember that you're taking constant battle damage so be sure you're not losing in the process, also preferably the opponent monster will have 1900 attack points or less so you take less damage than your opponent.
