As you can see, the party consists mainly of sweepers and baton passers, with my aqua ring milotic and ingrain cradily I believe I can baton pass to the sweeper of my choice to take down any pokemon in one hit-two hits.

Thanks for checking out my team, I hope some of you can help me out.

P.s please don't tell me to test it out as my ds is broken and I am getting a 3ds within this month.

I'll assume this is a UU team.

Cute Charm is a terrible ability on Milotic. It's not likely to trigger against opposite-gendered Pokemon and infatuation can be cured by switching anyway. If memory serves me right, it can't learn Baton Pass either. It's better off supporting the team with its high defenses:
-Scald
-Ice Beam
-Recover
-Toxic/Dragon Tail/Haze
Nature: Bold
EVs: 248 HP/252 Def/8 Spe
Item: Leftovers
Ability: Marvel Scale

or
-Rest
-Sleep Talk
-Scald
-Dragon Tail
Nature: Calm
EVs: 248 HP/196 Def/56 SDef/8 Spe
Item: Leftovers
Ability: Marvel Scale

Trick is better off on Choice sets. Porygon-Z's current set is seriously lacking in coverage here:
-Nasty Plot
-Tri Attack
-Hidden Power (Fighting)
-Dark Pulse
Nature: Timid
EVs: 252 SAtk/4 SDef/252 Spe
Item: Life Orb
Ability: Adaptability

or
-Tri Attack
-Dark Pulse
-Hidden Power (Fighting)
-Trick
Nature: Timid/Modest
EVs: 4 HP/252 SAtk/252 Spe
Item: Choice Specs/Choice Scarf
Ability: Adaptability

or
-Agility
-Tri Attack
-Dark Pulse
-Hidden Power (Fighting)
Nature: Modest
EVs: 96 HP/252 SAtk/160 Spe
Item: Life Orb
Ability: Download

Cradily can't learn Baton Pass either. Clearly, Smeargle is your best bet for BP'ing Ingrain, since it's the only Pokemon who can do so:
-Spore
-Ingrain
-Baton Pass
-*insert set-up move here, preferably Shell Smash*
Nature: Jolly/Timid
EVs: 80 HP/96 Def/80 SDef/252 Spe
Item: Focus Sash
Ability: Own Tempo

Druddigon can't learn Swords Dance; Hone Claws is the only Attack-boosting move it learns. It can't take on offensive and defensive roles at once; it has to choose one:
-Outrage
-Sucker Punch
-Earthquake
-Dragon Claw/Superpower
Nature: Adamant
EVs: 144 HP/252 Atk/112 Spe
Item: Choice Band
Ability: Mold Breaker

or
-Stealth Rock
-Dragon Tail/Roar
-Dragon Claw
-Glare
Nature: Impish
EVs: 252 HP/4 Atk/252 Def
Item: Leftovers
Ability: Rough Skin

As I said before, I'm assuming this is a UU team, so I'm replacing Forretress and Ninetales with something else, like, say, Hitmontop and Darmanitan:

Hitmontop:
-Rapid Spin
-Foresight/Toxic
-Close Combat
-Sucker Punch/Stone Edge
Nature: Impish
EVs: 252 HP/252 Def/4 SDef
Item: Leftovers
Ability: Intimidate

Darmanitan:
-Flare Blitz
-U-turn
-Rock Slide
-Earthquake/Superpower
Nature: Adamant/Jolly
EVs: 252 Atk/4 SDef/252 Spe
Item: Choice Band/Choice Scarf/Life Orb
Ability: Sheer Force

As you can see i'm not very experienced with team building xD, thanks for your help, i'll try and build an alternate team.

is garchomp still banned from competitive play because of sand veil?
