I want to do a 100% playthrough of Colosseum because reasons. This also means playing battle mode. I don't think my in game team will be enough in there, but most mons in Colosseum go from mediocre to complete trash.

What would you do? It doesn't have to be an extremely competitive team, just something to get the job done

Some good mons are
>heracross
>flygon
>metagross
>tyranitar
>raikou
>skarmory
>forretress
>medicham
>suicune

No idea if they're also good in doubles and if there's a way to combine them, help
