Ishtar is a Buster main so you technically CAN run her with Quetz so the latter can use her buster buff to the former while the former uses her Charisma variant to buff everyone's attack power and critical damage, but Archers have above-average star weight (the stat that determines how often critical stars go to a single servant's cards) while Riders have the highest; putting them together will have them compete for stars.

Though, in all honesty, it all depends on the situation; if you're fighting a bunch of Casters, you'll probably want, say, Medusa or Ushiwakamaru; if you're fighting a bunch of Sabers, you'll probably want Archers like Robin Hood. If you're fighting enemy waves with confusing compositions or more 'special' classes like Zerks or Avengers, go wild.
