I want to make a team around Hoopa-U but I'm not very convinced of the final result in the team I don't have defog or stealth rock so if you could improve it I would be very grateful

Hoopa-Unbound @ Choice Band
Ability: Magician
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Hyperspace Fury
- Gunk Shot
- Fire Punch
- Zen Headbutt
I start with Hoopa-U I chose a choice band set hyperspace fury is his best stab gunk shot and fire punch is for coverage and zen headbutt for second stab for nature i chose adamant but i don't know if jolly would be better EVs max Atk and max Spe to maximize offensive presence

Scizor-Mega @ Scizorite
Ability: Technician
EVs: 248 HP / 252 Def / 8 SpD
Impish Nature
- Bullet Punch
- Swords Dance
- Roost
- U-turn
to support Hoopa I need pivot user and I believe Scizor-Mega is the best to start its high Def compensates very well with hoopa's low Def for the set is the classic set bullet punch for stab and priority sword dance for boost roost for recovery and u-turn for pivot EVs max HP and max Def maximize fisical bulk

Kyurem @ Heavy-Duty Boots
Ability: Pressure
EVs: 56 HP / 252 Def / 140 SpD / 60 Spe
Bold Nature
IVs: 0 Atk
- Substitute
- Freeze-Dry
- Earth Power
- Roost
next i chose kyurem helps a lot against stall match up and rain match up for the set i chose the set Sub-Roost freeze-dry for stab earth power for coverage and roost for recovery EVs 56 HP is for 101 HP sub 60 speed for outspeed magnezone and the rest is to maximize bulk

Toxapex @ Black Sludge
Ability: Regenerator
EVs: 248 HP / 104 Def / 152 SpD
Calm Nature
IVs: 0 Atk
- Scald
- Toxic Spikes
- Recover
- Haze
at the beginning I wanted to put in the team tapu fini for defog and for check greninja but i didn't like the idea of having two tapu in the team so i chose toxapex for special wall and greninja check i don't know if i did well i hope you will help me in case for the moveset scald for occasional burn toxic spike for azard recover for recovery and haze to stop settup swepper EVs 104 Def con max HP allows toxapex to survive due knock offs from choise band weavile and +2 kartana's leaf blade from full HP the rest of the EVs go on SpD to maximize special bulk

Tapu Koko @ Choice Specs
Ability: Electric Surge
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
IVs: 0 Atk
- Thunderbolt
- Volt Switch
- Hidden Power [Ice]
- Dazzling Gleam
for the last two I need fast pokemon for pivot so I chose tapu koko as the first thunderbolt and dazzing gleam for stab volt switch for pivot and HP ice for coverage EVs max SpA and max Spe to maximize speed and damage

Greninja @ Groundium Z
Ability: Protean
EVs: 252 Atk / 4 SpA / 252 Spe
Hasty Nature
- Dig
- Gunk Shot
- Ice Beam
- U-turn
for the second fast pokemon I chose greninja protean because I lacked the z move and with gunk shot it supports hoopa very well for the moveset dig to use with the z move gunk shot main attack ice beam for coverage and generally I choose spike as the last move but i needed pivot moves so i chose u-turn instead EVs max Atk to maximize the damage of gunk shot and z-move and max Spe to maximize the speed hasty nature for not to lower the power of ice beam
