so ive been using a sun team recently so i thought id weigh in here.
im going to post my team to help you understand my thought process.
its not the best team but its actually been doing pretty well and has managed to beat sand and rain teams.
hopefully this helps you or anyone when building their own sun team
first and the most obvious is Torkoal
my nature and moveset i think is pretty standard
bold 252 hp/ 252 def
-lava plume
-stealth rock
-yawn
-rapid spin
at one point i was using an impish flygon with defog to come in on tyranitar so i experimented with replacing rapid spin with explosion.
but tbh i didnt quite like explosion much
for my special sun abuser i used either exeggutor or victreebel
exeggutor
timid 252 sp atk 252 speed
-psyshock
-giga drain
-solar beam
hp fire
i went timid nature since some popular scarf pokemon outspeed modest nature in the sun
sometimes i miss that added power of modest because blissey and chansey are extra thicc, but since everyone expects modest i can sometimes get them to switch.
i noticed you are using ancient power and i have very much considered it and in some situations i wish i had it, also that chance for a boost is nice.
i have both solar beam and giga because with opposing weather solar beam alone isnt as reliable
my physical sun abuser is sawsbuck
sawsbuck
adamant 252 atk 252 speed
-horn leech
-return
-jump kick
-swords dance
i read someone had mentioned no comparable sun pokemon to excadrill and kabutops, but this is definitely it.
this set is pretty scary to be on the other side of
Crobat
Naive 252 atk 252 speed, holding flying gem
-acrobatics
-uturn
-heat wave
-taunt
this is my spin on the standard crobat set
i use this to switch in on fighting moves
and i have heat wave to get some surprise kills on ferrothorn, magnezone and scizor. and its boosted in sun so thats a plus
acro with gem also does a good amount of damage on anything that switches in
magneton
timid 252 sp atk 252 speed
holding eviolite
-t bolt
-flash cannon
-hp fire
-metal sound
this magneton is solely to get rid of scizor who is a big threat to my sun sweepers with bullet punch
eviolite gives it some added bulk and timid nature allows me to outspeed certain pokemon and i can bluff a choice item
metal sound comes in handy sometimes but volt switch might be better
lanturn
calm 252 hp 252 sp def
-volt switch
-scald
-heal bell
-toxic
pretty standard set, the main reason this is here is for togekiss and to have something for hydreigon
it doesnt really do well against hydreigon but it allows me to switch in a couple times and try and get one of my sun sweepers in and scare it off
this teams has some flaws but it wins enough for me to keep using it in match making
i really recommend some hazard control as rocks will ruin torkoals day
i dont really know what else to add but if yo want some more help id be glad to give more input
