So I am trying to do this gym for quite a while now.

As of you guys speaking the gym should be around level 6x10 + 5 = 65.

 

Which i can't understand that well.

 

My team at this point is: TEAM

 

I've been trying to level up my pokemon because the gym should be around level 65, but the highest pokemon which i can find are level 33.

I can train my exeggutor and flaaffy allot here, but the other pokemon are hard to train.

 

This psychich gym is so hard to beat, she insta kills my pokemon.

 

Can some 1 give me tips where to train or what to do?

you can train in seafoam

surf to west from fuchsia city, route 19

the reason why your pokes' level can't catch up because you train too many pokes

you will have to train more for gym7 after gym6

Sabrina is just like the previous gym leader prefered charizard to match up agaisnt her other than that most poke types dont fare well agaisnt sabrina

I had to balance out the line up when i got to sabrina because quick leveling guide does not fare well agaisnt gio

What you mentioned about levels is around the rule of thumb for gyms but it all depends on the team you're using. Sabrina is probably the hardest gym for the unprepared in Kanto because there are so few decent dark, bug or ghost pokemon available early on.

 

You can catch both Gastly and Duskull at pokemon tower 7F. They are both relatively easy to train at Diglett's cave as they both have levitate. Once you've got their level up then go to seafoam as hahahaka suggested. Although be careful with Gastly as it has a psychic weakness.

 

Another option is to catch a houndour or murkrow on route 7. As dark types they are immune to psychic damage.

 

As hahahaka mentioned the best place for you to level right now is seafoam island, go to seafoam B4F, it has the highest level pokemon and also has a nurse joy ther who'll heal pokemon (for a small price) so it is a handy place to grind at your current stage in the game.

It implies that a better defensive strategy should be applied against psychic because Sabrina has the same skill tree as earth badge that is why a balanced strategy will fare well against both

Use dark type pokes or dark moves if u want to beat sabrina just train a gastly upto lvl70+ he will sweep pokes at once or gyara is also a gud choice with dragon dance total OP;)

Thank you guys!

dark types work well or maybe fire types for xp boost I think that it would be 40 to 60 in levels because of how late game Sabrina is

Thanks allot guys! Just 10 min ago i became the Hoen champion. So thanks for the help!
