Overtrump → It is formed from "over-" (meaning above or beyond) and "trump" (from Middle English *trumpen*, meaning to sound a trumpet or to surpass). The word means to surpass or outdo someone, especially in a competitive context.
Think of going 'beyond' ('over-') to 'surpass' ('trump') someone in a competition — that's what overtrump means.
