If I don't want hurricane or confuse ray to confuse me what do I do? If I don't want to get burnt by scald what do I do? If I don't want to get critical hit what do I do? I could go on with a lot of examples but I think the point is clear.
If your answers are the lolish use own tempo/fire pokes/that trait that prevents crits. Then I've got a lolish answer to your question: use moves that don't miss such as aerial ace.
Also thank you Seth Vilo. I also agree with hipmonlee.
The question isn't about avoiding hax entirely. It's more about it not being very effective. So what if I get confused? I would switch out, or if I'm feeling adventurous, try to attack. If I know an opponent has scald, I might switch to a Poison Heal user or Reuniclus. Now critical hits are a different matter. A user can't really change critical hit ratio without major changing to movepool, and if so, switch to your appropriate wall and assume that all hits will be critical hits. Burn the pokemon, toxic, something to limit its lifespan / power. It's not a big problem apart from lower tiers, with abusers. Evasion has no "easy way to make it less effective". It needs to be controlled.
