When viewing Pokémon solely as a competitive, numerical game then the quote is irrelevant. It argues in favour of a more emotive and holistic perception. I actually agree with it more than I disagree in terms of overall worldview, but I also realise it isn't best applied in the context of a game with operating on binary logical rules...
Even, so, for random wifi battles I'll probably find the best compromise between effectiveness and subjective bias that I can. I would prefer to use Pokémon I consider favourites even though such sentiment is largely irrelevant in a competitive context...
"Perfectionism becomes desirable when it stimulates the healthy pursuit of excellence."
"Truly skilled trainers should try to win with their favorites."
The operative word there is "try." Just because it's your favorite, doesn't you'll win with it.
I like Farfetch'd. But have I excluded him from nearly every competetive team of mine because he sucks? Yes.
That message is poetic. And works in the storyline of Pokemon. It's about friendship and trust. Games are based on numbers, however. And gameplay dictates that there ARE in fact strong and weak Pokemon. It's not up to selfish perceptions. It's up to hard-coded numbers. And numbers don't lie.
I manage to win with a Farfetch'D against competitive team. What the hell were you even running?
