Usually people use the following team to fight Archwitches/F. Archwitches:

2x Enemy attack debuffers

2x All allies heal, infinite proc

1 damage card, usually using infinite proc 350% attack damage

You can replace that damage card with the card that holds the skill which you want to test. Debuff teams without a strong attack card can stall to 100 turns where the archwitch flees without being subdued.
