The power of a war god
At the moment, Vincent was feeling pretty relaxed about the situation he was in. Although he didn't have Quinn's shadow powers outside, since they would be fighting in a game, 'his' avatar would have them.
Of course, Logan was unable to input the exact amount of MC cells that Quinn could control. During the test his MC cells seemed endless and since this was just a game and Quinn had already displayed his powers he asked Logan to just put a high amount. Win or lose it didn't matter to Quinn since the results didn't matter. All that mattered was the outcome in real life.
Another thing was replicating all of what the shadow could do, it was a hard task with limited time, so Vincent would only have access to the basics. However, in the tenth leader's mind that should be more than enough.
