Hi there, someone teel me that sun is the weakest weather in the metagame and in VGC, but I think that a good player can win also with the sun. I prefere this team to a sand one or similar, also if my team is not completely sun abuser, so that's the team:
AT A GLANCE:

IN DETAILS:
Weavile @focus sash
Pressure
jolly
252 atk 252 atk 4 def
-fake out
-ice shard
-protect
-night slash
Weavile is the fastest fake-out user, priority STAB ice shard is great, and his stats are very good too, 120 atk and 125 spe. Max atk and speed to hit hard pokes like cresselia, jolly to outspeed 90% of the metagame, focus sash to survive an hit.
Protect, Fake out and ice shard are obvious and night slash is for STAB

Blaziken @life orb
Speed Boost
adamant
252 atk 252 spe 4 hp
-flare blitz
-rock slide
-sky uppercut/hi jump kick
-protect
This is a beast in singles, is my favorite pokemon, with speed boost outspeed everything and in the sun can hit hard each pokemon.
I preferred adamant to jolly for more power. flare blitz is a great STAB, rock slide provides coverage and hit both opponents while sky uppercut is to avoid risks with protect. The only pokemon that can wall it is jellicent, but weavile can hit him very hard and also OHKO and flare blitz in the sun is dangerous for him.

Thundurus @charti berry
Prankster
timid
252 spA 252 spe 4 def
-thunderbolt
-hp ice
-taunt
-protect
Why this pokemon instead of Zapdos for the combo with Garchomp? Because I want a priority taunt and a good speed. Thundurus can outspeed Garchomp and OHKO him with hp ice if he doesn't have yache berry, and also if he has yache berry a combo with sky uppercut+hp ice or just ice shard+hp ice easily KO him. Charti berry is to survive a rock slide. Furthermore he can OHKO jellicent who is a problem for blaziken

Garchomp @yache berry
Sand veil
jolly
252 atk 252 spe 4 hp
-dragon claw
-earthquake
-rock slide
-protect
This is a standard Garchomp, it means that this beast can do serious damages to everything. dragon claw over outrage to avoid to be locked into one attack, earthquake and rock slide for STAB and coverage respectively. Jolly to be faster and yache berry to resist hp ice or ice shard.

Cresselia @sitrus berry
Levitate
bold/relaxed
252 hp 200 def 56 spD
-icy wind
-trick room
-psychic
-protect
This pokemon can wall very well in every team, and like saboros says: if you can beat them, enjoy them. with a bold nature to wall phisical attacks like dragon claw or also x scissor. Icy wind is helpful and can low the foe's speed and it is great for thundurus and garchomp. psychic for STAB and protect is obvious. sitrus berry is a good way to regain health. trick room is to stop other trick rooms.

Bronzong @occa berry/mental herb
Levitate
sassy
252 hp 164 def 92 spD
-sunny day
-light screen
-trick room/gyro ball
-protect
This pokemon is an amazing wall that can survive a Conkeldurr's hammer arm or a chandelure's heat wave and reverse the trick room or put screens. Occa berry is to survive a chandelure attack but mental herb is to not be killed by taunt. i'm not completely sure about this pokemon and a good replacement can be whimsicott with taunt, encore and trick room. with bronzong thundurus is neccesary with prankster but with whimsicott also zapdos shuld be try.
SO this is the team i want to bring to the VGC at the moment, but there is still a lot of time so any suggest and criticism is much appreciated. I know that is not perfect and probably i will not win VGC with this team but I want to perfect it. thanks in advance for the help :)
