Counter Question?

If Sarissophoroi are good vs archers, and Prodromos are good vs Calvary, which are good vs Chariot Archers? One? The other? Both? I feel like I'm trying to guess the counter for Manbearpig. . .

Al Gore counter ManBearPig.

I consider Chariot Archers as cav since thats the barracks that makes them. I'm probibly wrong.

|||chariot archer dont have the cav tag, they only have the archer tag, so prodromos dont have any bonus vs them, saris on the other hand have a bonus vs them
