And I'll answer all but two of the OP's questions in one fell swoop.
Who is your favorite Yu-Gi-Oh! character (or duelist) and why?
-> Syrus Truesdale, he is so under appreciated and has the potential to go far.
Which of all Yu-Gi-Oh! Cards is your favorite card and why?
-> Tempest Magician, currently it is my most expensive card, and it's a staple in my deck.
Which Yu-Gi-Oh! do you like the most? The Original one, the newer or the newest and why?
-> The original one, it introduced us to the game and laid out the framework for what we have now.
Which type of card do you prefer? Effect-monster, Trap, Spell, Ritual, Fusion, Normal or synchro and why?
-> Normal Monsters. I run a whole deck of them, and they have major support. And flavor text RULES.
What do you like most about Yu-Gi-Oh!?
-> The fact that I get to meet new people at tournaments (even though I've never entered an official one.)
Are you obsessed with Yu-Gi-Oh! or just a (big) fan of it?
-> Just a fan.
What kind of deck do you have (IF you have one)?
-> 14 currently:
What is your favorite millenium item and why?

If you could add any card(s) to the ban list, what would you choose?
-> Any "Blackwing" or "Saber" monster, those decks are too powerful.
Which archetype do you like most and do you think is the most powerful?
-> Blackwings/Sabers (the ones that I can't beat yet)
What do think of the new Structure Deck that is coming out the 27th of October?
-> Average, I'm just getting it for the playmat.
What are your best pulls?
-> Armory Arm from my first Duelist Pack - Yusei
-> Dark Paladin from my first Duelist Pack - Yugi
-> and my favorite: Imperial Order from my first pack ever, a Metal Raiders 1/e.
And now the newest question:
My thought-best Synchro Monster
is either the aforementioned Tempest Magician or the ever so broken Cosmic Fortress Gol'Gar.
