In fate, Red A and Big Dog (Five Gunmen Cavalry) tried their best. Who is more likely to win?

Actually, Kuchulin is very strong. If it weren't for the curse, it's hard to say who could beat him in the fifth Grail War.

For Red A, if the gun that pierced the dead thorn can be taken out, there is a great chance of winning. This move can only be avoided by luck, and opponents with poor luck will be killed. Saber got away with it once when he didn't get Avalon, and it's hard to say later. Lucky e with red a cup is almost inevitable. The only exception is Bazett, who was hit by a more abnormal backlit sword.
