Yu-Gi-Oh/Expert Profile

Expertise

I'm able to answer any and all questions related to the English Yu-Gi-Oh! game itself. This includes, but isn't limited to:

Deck Fixes: These can either be making suggestions and improvements on a deck you've already built, or building a deck from scratch for you. In either case, please give an idea of the kind of deck you're building, the level of play you're planning to use it in (fun games, small tournaments, regionals etc), and roughly the kind of budget you're on.
Please format decks in a way that's easy to read. The standard way is to put each card name on its own line, with a number before it indicating how many you're playing. Please split decks into Monsters, Spells and Traps.
I can offer fixes for OCG (Japanese) decks, but please allow more time in this case, as I may need to research some of the cards you're playing.

Rulings: On any card interacting with any other card(s). Just tell me the scenario, and I'll tell you what happens. Any rulings that can be linked to Official sources will be, so that you can see the official word on the matter. Any rulings that can't be linked will be explained in full, so you understand the reasoning behind my decision.

I won't be answering questions on whether a trade is fair or not, or on how much X-card is worth, as both these kinds of question can be answered by using Ebay's completed listings page.

What do you like about this subject?

I enjoy games between two non-top-tier control decks, match-ups purely about skill, not who can drop the most Boss Monsters in the shortest period of time.
Angelic Chaos and Space Debris are some of my favourite decks this format, simply because they're enjoyable to play.

Something interesting about this subject that others may not know:

Mantis ranks players with equal wins using 3 Tiebreakers:
T1: Gain 1 for every match that the people you beat won, and lose 1 for each match they lost. If you won 2 rounds, with people who went 3-2 and 4-1, your T1 is 3+4-2-1=4.
T2: Is the same as T1, but for players you lost to.
T3: Is the sum of the squares of the rounds you lost in. If you lost in rounds 3 and 5, this is 9+25=34.
