Is there a single servant or servant team (like Charlemagne's Paladins for example) who could beat the Knights of the Round Table in their prime? As in:
Artoria with Excalibur and Avalon
Gawain under the Sun
Percival with the Lance of Longius
Agravain with Madness Enhancement
Galahad with the Shield of the Round Table
Bedivere with Airgetlám
Lancelot
Tristan
Gareth
