It depends, you could have a good commander and a terrible deck, or vice versa, but I personally think that Arcum Draggson is the best commander. There are some erally sick combos with that guy.
All lands! :P
His best deck has to be the one in episode 147-148
the annoying spellcasters
The best Yu-gi-oh player is Yugi because he started and has the best deck!
Your best bet is a cyber or cyberdark deck, with cards like Cyber Dragon for Cyber and Cyberdark Keel for Cyberdark.
All lands! :P

Generally you should play a deck of the minimum allowed size, this helps to increase the decks consisency. The minimum allowed deck size depends on the format that you will be playing, for modern, standard, legacey, vintage, and casual it is 60. EDH/Commander allows a minimum of 100( one commander and 99 in the library). Limited (decks built while drafting, or sealed) has a minimum deck size of 40. For a deck of 60 the baseline number of lands is 24, for a deck of 100 the base line is 37, and a 40 card decks baseline number of lands is 17.
The best deck is what you like and how you use it, there is no best deck just like water puts out fire and so on there is always a meta-deck that will always beat another meta-deck.
