So Uria's this monster, and he becomes more powerful based on how many continuous traps you've got in your graveyard. All right, that's OK. Then there's this spell called Reasoning, that mills cards off your deck until you hit a monster. You know, if you Reasoned while Uria was on the field, he'd turn into some kinda horrible fangly fish. You could do something with that.
This is the evolution of another deck I built that relied exclusively on traps to lock your opponent down into being unable to do anything. In the end I decided I'd prefer to summon an 18000 ATK beastie and hit them for max damage through the D.D. Lady they thought would protect them. Most of the combos are pretty obvious. There's two Japanese-exclusive cards in it, but effects are provided. Let's see, the monster set works perfectly well, when you consider that I actually have 15 monsters in the deck, counting Reasoning (worth a monster as long as they don't say 3) and the two trap monsters. The magic set's OK, I went with 2x Trunade instead of 3 because of Uria's trap-killing ability, Monster Reincarnation is in case Uria hits the grave you can discard a trap and get him back. Mostly I want you guys to monkey with my trap selection, I know something better can be done but I don't know what. I present: Reasoning of Flame Emperor.

* Dead Spirit Zoma: continuous trap. Special summon this card to your monster zone in defense mode. It is treated as DARK/Zombie/4/1800/400. If your opponent destroys Dead Spirit Zoma as a result of battle, deal to your opponent damage equal to the ATK of the monster that destroyed Dead Spirit Zoma.

** Metal Reflect Slime: continuous trap. Special summon this card to your monster zone in defense mode. It is treated as WATER/Aqua/10/0/3000.

yes i think cyber dragon needs to be here for reasonings sake it's a level 5 monster that is'nt going to be that bad in your hand anyway. after that I made a few minor tweaks to the trap layout and put in a copy of outstanding dog marron. while you may laff at it at first it's an extremely technical piece for this deck. If the deck runs into troule geting the otk off at first marron will try to keep you from decking out and also from running out of monsters to be found with reasoning.

- Anti-Magic Fragrance

+ Spirit Barrier
+ Blind Destruction
+ Fake Trap (in case they use some monster to destroy your traps...)

Makron: I'm with you on the Marron thing, but I've been careful with my Reasonings so far ("Let's see, I've got two Spirit Reapers and a Sangan in the graveyard, maybe I should just let Uria be a 7000 instead of a 13000 this game") so I've been OK with it. Cyber I agree with, so that no matter what they call I have a shot at getting a monster, I'll try and work it in. Can't believe you lost Light of Intervention and Final Attack Orders, though, that's an extremely important combination. Makes it so that no monster can turn into an impediment for the great and powerful Oz. I mean Uria. Oz is a more different card. Also, given that you added more monsters, the Embodiments of Apophis are even more useless. On attack Zoma's better, on defense Slime's better, and as a trap Tower of Babel was better because it seems to get up to 3 counters in a hurry and makes my opponent very scared to try Smashing my Uria.

Pyro: Why Blind Destruction instead of Needle Wall? Blind D can kill my guys too, iirc, which outweighs the chance at multiple kills. On the topic of Fake Trap, well, I don't mind in the least if my traps get destroyed, I'll always have more =P and it just puts more traps in the graveyard for Uria.
