Ferrothorn can freely switch in taking 25% max and can force it out via leech seed, gyro ball, and can potentially use it as set up fother. After a geomancy boost xearneas is cleanly 2hkoed by gyro ball and after rocks it is guaranteed 2hko'ed. Once you force out a power herb you can use it constantly for free spikes and free recovery via leech seed with it + protect
