The first two mons look normal, but the last one is the one that catches most people's attention. Out of sand, Mega Garchomp is a pretty underrated threat, as it has not-that-high speed, letting it get outsped by many things and be KOed easily. In Sand, however, it receives a huge buff to its offensive potential, powering up its Earthquake to monstrous levels. Tyranitar sets up the sand for the two next members, and Excadrill functions as a fast threat with Sand Rush and Garchomp, with its huge attack stat, destroys almost anything in its path, especially with Sand Force helping it along. Support Tyranitar Thunder Waves threats than can otherwise outspeed Garchomp, and helps to pave the way for a sweep.
