He is talking about a 1 vs 2 (Shisui vs AGK + EGK). Which Shisui would never win, unless you are a complete idiot.

That being sad. AGK has never been convincing in Arena.

AGK is very squishy for a position 1 ninja. Which is why most people play her with a main.

But srsly, if you wanna conquer your shisui trauma, just replace EGK with Masked Man.
