Resto Chesto, one the most infamous and effective combos in the whole Pokemon metagame because of three specific reasons. Firstly until you pop the rest or they spore you, your opponent will have no idea what item you are holding giving the surprise factor as well as making them think you could be holding a different item such as an expert belt or choice scarf. Secondly having this combo also makes you pseudo immune to poison, paralysis, and burn because when you rest it negates the status. Lastly, and possible the greatest benefit is how it can safely bring you back to full health in one turn possibly saving a poke or starting a potential sweep. It's most notably known on such Pokemon as Rotom-Wash and Kingdra, these however are not RU and this is where you come in.
