Doublade

After the Aegislash ban, many powerful wallbreakers that Aegislash stopped now roam free without having to run additional coverage to get past it. By virtue of its typing and natural bulk, Doublade fills the void left by Aegislash's departure. Its ability to beat the likes of Mega Heracross, Mega Medicham, and Mega Gardevoir makes it a popular choice on stall teams. The fact that the metagame stopped preparing for its defensive typing after the Aegislash ban, such as Mega Medicham forfeiting Fire Punch and Mega Pinsir, Mega Heracross, and Terrakion forfeiting Earthquake, gives Doublade the ability to completely stop a few important threats. Its immunity to trapping is a huge advantage over the likes of Ferrothorn and Skarmory, which need to run Shed Shell to avoid Magnet Pull from breaking them down. Unfortunately, Doublade's ability No Guard makes all moves used against it, notably Hydro Pump, Fire Blast, and Will-O-Wisp, always hit. Doublade's Special Defense stat is also very mediocre, meaning it gets worn down by a few things it is supposed to counter, namely Mega Gardevoir, Latias, and Latios. Doublade also suffers from a lack of recovery apart from Rest, making it require Heal Bell support to function efficiently and wall threats consistently.
