Is my Rock/Ground/Steel type team Legal for Random Matchup?

When I first put them in Random Matchup, it said that there was a problem with my Pokemon, so that I had to go change them so many times so they can be legal, and it said the same thing. This frustrates me alot. This is my team:

Tyranitar
Ability: Sand Stream
Holds: Leftovers
IV: 499
Moves:
Protect
Ice Beam
Rock Slide
Earthquake

Aron
Ability: Sturdy
Holds: Shell Bell
Moves:
Protect
Endeavor
Roar
Toxic
IV:369

Scizor
Holds: Life Orb
Ability: Technican
Moves:
Bullet Punch
X-Scissor
Swords Dance
Aerial Ace
IV:510

Torterra
Ability: Overgrow
Holds: Rose Incense
Moves:
Curse
Leech Seed
Seed Bomb
Earthquake
IV:510

Nidoqueen:
Ability: Poison Point
Holds: Quick Claw
Moves:
Earth Power
Flamethrower
Ice Beam
Thunderbolt
IV:510

Landorus
Ability: Sand Force
Holds: Fighting Jewel
Moves:
Rock Slide
Earthquake
Brick Break
Swords Dance
IV:502

And that I checked their IVs 10 times, their IVs are between 490 and 510. Plus I didn't place fateful encounter and that I exactly put the right info on them, their IDs, their PIDS, their natures, and their stats. I just don't know why they can't be in Random Matchup, but they allow Landorus to be in there, a lot of trainers bring one. Plus I put that Landorus is at LV 70 and that it was met at Abundant Shrine at LV 70.
