This is another very good combo.Here is more slow,but anyway if you made this=GG.Let's begin with necessary cards:
Quillbolt Hedgehog

If you control a face-up Tuner Monster, you can Special Summon this card from your Graveyard. If this card was Summoned this way, remove it from play when it is removed from the field.

Cannon Soldier
Offer 1 monster on your side of the Field as a Tribute to inflict 500 points of Direct Damage to your opponent's Life Points. Monsters used for a Tribute Summon or that are offered as Tributes due to other card's effects are excluded.

Imperial Iron Wall
Cards cannot be removed from play

Any Tuner Monster(preffered plaguespreader in grave to can normal summon cannon soldier and make OTK)

First we must have Quillbolt Hedgehog in graveyard and set Imperial Iron Wall.After that we summon Cannon soldier and activate Imperial Iron wall.Summon the tuner(i told you that plaguespreader is preffered cuz isn't normal summon but anyway) and then summon Quillbolt Hedgehog from the grave.Activate effect of Cannon Soldier to tribute Hedgehod.Since cards cannot be removed from play you can activate the effect again and again to kill your opponent...this is so broken,youcan try it !

P.S This combo will works better with Mass driver since we do not need to summon Cannon Soldier and we can normal summon the tuner.

Easier is to use Mass Driver so u don't have to summon Cannon Soldier. It's been a well known combo ever since Quillbolt was released. There were even Quillbolt OTK decks created for quite awhile, but they were very fail because the combo isn't as easy to pull off as you might think.

Yea and must to say this is so hard,i tried not little times and always when i almost complete the combo my opponent always make something to stop it..
