Can someone tell me how I can keep a snorlax streak and get a 6 defeat streak? Almost all of my pokemon are at least level 1000 and the other two are very low. Can someone give me advice?

I think it goes like toxic then close combat every snorlax. Make sure you save your toxic pokemon so you can defeat snorlax.

you need the move toxic and u need any fighting type move to be able to defeat more snorlaxes

i heard that you need to use Spiritomb to beat the snorlaxes.

Yeah use a team of spiritombs to get a large win streak make sure they know fighting moves.

When I used Close Combat on the second Snorlax and afterwards it wasn't super effective so it may take more then that, they use Surf, Seed flare and hyper beam I think.

use a party of 6 golurks very close in levels with each other..have toxic and fly on every poke and also close combat..i think using these u will get a 6 streak pretty easily
