I need some help, /vp/. I can't quite say that I am competitive, but I want to be.

It's disappointing that you're at a disadvantage if you just want to pick 6 of your favorite Pokemon and call it a team. I've learned the hard way that it's never going to work out based on how Pokemon game mechanics have been engineered.

Tiers, as I understand them, are actually pretty neat so that people can work with what's realistically fair in battle while maintaining the use of their favorite Pokemon.

But it's sad, as the game's mechanics are engineered, that particular Pokemon always end up getting grouped together in the same party for a super strong team.

I almost always see someone using a Rotom on their team when I'm in the mood for Random Matchup on X/Y. It's really getting boring.

Although, I feel like I'm misunderstanding this all, can someone give me some ideas to compete without looking at it this way?

I want to be competitive without the boring shit.
If anyone could offer me resources, or advice, I would greatly appreciate it.

I want to know what the ideal set up is for a team, and what to look for when creating a team. I know that I could easily look this up, but despite all of the bait that circulates /vp/, I'm sure there are plenty of experts here that could give me some solid advice.

I'm going to leave a list of my favorite Pokemon if you have some suggestions:

Absol, Altaria, Corsola, Dedenne, Gallade, Latios, Masquerain, Meganium, Metagross, Milotic, Porygon (the whole line), Shaymin, Skarmory, Steelix, Suicune (my absolute favorite), and Sylveon

With Suicune being my favorite Pokemon (ever), I know that the most popular strategy is CroCune, but it's really boring and I was kind of hoping for using Suicune as an offensive part of my team.

Also, general noob competition help thread, so that it's not only about me.
