What cheap champion is best for powerfarming the CS based missions in short AI games?

Well since Sivir is known as the champion who will have twice the enemy ADC's cs while still doing half their damage I imagine she's a good pick for farming

mordekaiser literally devours waves

tbh I find all champs to be very affective with perfect CSing good luck hope this help!

Singed

Any ADC that can use Hurricane.

Any ADC or full AD Garen
