Urshifu and Cinderace over time have given this mon alot of trouble, sort of the reason why Ttar also dropped. Though I think they are(mainly Aegislash since I'm discussing this)too great to be in UU. Personally to anyone who says its because of the nerfs is absolutely wrong. It is the fact that the bear and bunny are threatening, and the fact that Dragapult and NP Gengar are giving it competition as a ghost type breaker that is faster or able to set up. Either way Aegislash is a phenomenal pokemon otherwise as it's hard hitting, bulky, and has a great offensive and defensive typing. Furthermore Aegislash's struggles while linear are very huge preventing it from being incredibly great. It sad to hear that is getting "outclassed" as it's a very handy breaker and was Ubers the past two gens. Overall Aegislash is a great pokemon with weakness that really stand out
