Defintion of a weakened team?

Question

I see that many physical sweepers have a discription of.
"Is capable of sweeping after opposing team is weakened"
Which means what?
That walls are disposed of, or ALL Pokemon have taken damage prior to being swept.

Answer 1

Weakened teams can have lots of definitions. But for Physical sweepers:

• The team is weakened through damage, either passively or actively.
• Hazards are laid down, allowing the sweeper to take it down without worrying that it will survive.
• If the Physical wall is weakened or taken down, then your physical sweeper will have no problem taking the team apart.
