The Wailord deck was a special case. As you say, it was designed to stall out the opponent's deck, since if you start your turn unable to draw a card from your deck, you lose. It's a win condition that a lot of newer players fall for and hate, but it's in the rules.
In general, competitive TCG is far more focused on trainer cards than on having a lot of Pokémon and Energy. There are a lot of reasons, but the gist of it is that there's no point waiting to draw a Pokémon randomly if you can instead guarantee getting a trainer card, which lets you get another trainer card, which lets you choose which Pokémon you want.
There's no point having twenty Pokémon in your deck if your opponent only needs to KO 3-4 to win.
Also, the meta has changed a bit in the two years since the link you posted was written. Sun & Moon is more evolution focused than back then. You've also completely skipped over night march, Greninja's relevant period etc.
