Jirachi B>A- :
Jirachi got a raise this month due to the Z-Happy Hour set allow you to pass Skarmory with Thunderbolt and not taking many damage from Body Press, allow you to hit Clodsire harder with Stored Power/Iron Head, pass many Fairy type such as Hatterene and Azumarill due to a good coverage! His rise shine in many Ninetales-Alolan team!
Aegislash A+>A-: Hoopa/Ttar being super common more ttar due to the Knock Off addition doesnt really help Aegislash to shine in the current metagame! It is still does have a niche to pass Metagross but being worried about a potential Knock Off can be scary. Clodsire not helping also if full special atk and not being offensive to deal a big amount of damage.
Toxic sub still shine in the current meta vs stall but less efficient.
