Competitive Pokémon tends to go back and forth between times of “stall” (turtling) and hyper-offense (aggression) dominating the metagame, depending on which strategies and team builds players will find. Whenever one becomes dominant, fans of the other will constantly hound tournament runners to change tiering or ban certain pokemon to change it.

As for a “fun” game to go hyper-aggressive with zero HP, max damage, I’ve seen some YouTubers attempt “Danger Mario” runs in the first two Paper Mario games, maximizing FP and BP and never taking HP when leveling, keeping Mario in the “danger” zone where lots of evasion or damage badges will stay activated. They then rely on those badges, items and partner abilities to avoid taking damage.
