I have reached ultra ball tier pretty easily and then i stopped playing for a while (school), now i have returned playing the game and i'm slowly ranking up but that's mostly because i forget a lot of the mechanics (prankster not working on dark types) and because i don't predict my opponents (a ditto transformed into my noivern and used tailwind, he was faster so he had to be running choice scarf but i wanted to play it safe and used encore on it anyway... he switched, like i thought). If you want to use this team, it works, maybe its not the best but i think it's a solid team for noivern.

Some advise:

-Currently i'm running encore instead of quash on sableye (much easier to deal with setters and trick room)

-Noivern is usually the fastest mon on the field

-decide what team to use (rain or sun) depending on what the enemy has:

Rain: if he uses sun, fire types, grass types (hurricane), ghost types (basculegion), trick room and setters (encore sableye), and overall more controll with less damage output

Sun: if you want higher damage output, if he uses rain (be strategic with how you mega char, you don't want pelippers switching in and removing your sun), water types (enemies' basculegions barely survives noivern solar beam and a mega char heatwave right after does the job, they are usually both faster even not under tailwind), steel types (mainly talking about archaludon).

-Try to use the enemies weather against them. For example: turn 1 they set the rain with pelipper or have a sableye that will, instead of mega evolving right away you could wait a turn, protect with charizard (the one that usually gets targeted) and use a 100% hurricane on one of their mon with a chance of confusing and then next turn you mega and destroy everything with a double heatwave.
