>>46781610I recommend you using a Trap Scarf or Goggle Specs for Wish Cave. It makes really hard for you to lose. Wishing for some Pokemon is way faster than trying to recruit and evolve them, so you better get good at this dungeon.
Take a Pass Scarf and X-Ray Specs with you so you can only lose to bullshit like Earthquake or Paralysis.
I used Kecleon but I'm sure you can also do it with other strong mons. If you do it this way it will become foolproof. Don't give Sticky traps a chance.
Also Walrein is the Pokemon that takes the most EXP to get for some reason, so it's faster wishing for one.
