It goes against tournament rules due to the ban/restrictions constantly being placed (and taken off of...) pot of greed, but here it is:
this combo will allow you to win on turn 0 if you are lucky enough to get it.
hand:
dark room of nightmare
meteor of destruction (x3)
soul of fire (links to infernal flame emporer)
pot of greed
Draw 2:
restructor revoloution(x2)
Dark room of nightmare (as you should all be aware) increases the damage of all effect damage by 300 (aside from its own) so this is played first.
meteor of destruction is played next due to its "not applicable" effect (3000 LP or less-no damage) Now, thaks to DRoN, its damage is buffed up to 1300, making the total of all three spells 3900 in one round.
Soul of fire lets you remove one pyro in your deck and deal half its attack as effect damage, which would normally be 1350, but due to DRoN it is buffed up to 1650, adding this into the previous 3900 raises you up to a total of 5550 damage
the restructor revoloutions drawn by means of pot of greed do 200 damage for each card in your opponent's hand (and their field, but their hand is enough) since this is the beginning of the duel, they automaticly have 5 cards in their hand, totalling up to a grand 1000 + 300 damage, so chock on another 2600 to that 5550 making it 8150. they have been beaten on turn 0. show them that it's completely fair and that you didn't cheat, if they still don't accept the victory let them shuffle and duel again. if it happens almost the exact same way, laugh. hard. in their face. if not, let your hoards of direct-damage dealing denizens devistate them.
if my math is off however (and it probably is) replace RR #2 with a pot of greed, and draw it and Ookazi on the draw of that pot of greed. ookazi will be buffed up to 1100 thanks to the dark room.
