There was one card series that focused on conflicting colors (the Invasion cycle, if I recall correctly). But if you're looking to play tournaments, that may not be an option.
While it can be fun - and satisfying - to design a deck to counteract the playstyle of one particular person, you may be better off designing a deck that will work for any situation that you may come across. In my own experience (before I quit playing years ago) was to find a card or two that you really, really like and try to craft a deck around that (one of my favorites was the Spiritmonger,
which I nicknamed "Audrey," because the more you fed it, the bigger it got. combine that with an Armadillo Cloak
...). Remember that you can have up to four copies of a card in your deck, not counting basic lands. The minimum amount of cards you could have in your deck was 40, which is what I often chose to do, because it increased the likelihood of me drawing one of the cards I had based my deck around.
Yes, I tended to play weird things. A lot of times, it didn't work. Sometimes it did, with stunning efficiency (one deck I designed was all red. The only "creatures" were walls, and damage was done with direct damage cards, such as Kindle
or Urza's Rage.
