Min records with a friend with level 40-50 Pokemon go to his secreat base and battle him/her you can only battle once a day though
Honestly Sneasel's are weak. The combo of it's type they could at least make it a special sweeping monster. Good thing there is an evolution with Sketch.
mix records w/ pokemon that are weak to ice or dark
oops i thought he meant that only his sneasel died in battle at E4, u probably need to focus on the rest of your team if u can't win with lvl 60 pkmn-- i got through with lvl 50 pkmn so u should probably invest in lemonades(cheaper than max potion and most pkmn don't have a boatload of HP your first time through E4) or full restores plus revives, that should get u through without too much trouble
