DracoSlash has already been mentioned under various pairings throughout this thread.
-I'd just like to catergorize the whole idea of the core under one name because the core itself has so much potential to work on any type of team!
Of course, the (Klef)Key to the core is the newfound wondermon,
Aegislash.
As what can only appropriately be named 'Fairy's Bane', the way it can deal with the Dragons' new weakness is currently the most efficient I've personally seen this gen. This of course is reason enough to pair it with the powerhouses of generations past; yet an even more relevant reason is evident.
Its diversity.
For example:
Need something to
take physical hits and retaliate, while carrying a
strong priority?
Aegislash@ Lefites
Careful
252HP/132Atk/120SpDef
-King's Shield
-Sacred Sword
-Iron Head
-Shadow Sneak
To take a hit; an Ice Beam/Dazzling Gleam for
Garchomp or
Dragonite; before either inducing mind games with King's Shield or getting a solid enough hit away on either what it's checked or what switches in for it. Possibly forming a
defensive core and working a
bulkier offensive stance, something tipped to be ever popular this gen

Something packing a bit more 'strongth'? Maybe a secondary sweeper? Maybe even your
primary offensive threat?
Beastislash@ LO/Lefties
Adamant
252HP/252Atk/4SpDef
-King's Shield
-Swords Dance
-Shadow Sneak
-Iron Head/Sacred Sword
Like a truck, this will mow down the remains of teams. Chipping away at the opposition's defensive threats with Dragon's is
much less stressful when you know
you have this monster covering their backs. Hydreigon's new Fairy check will still
fail to really dent this mighty shield as it dances in their faces, and other offensive and faster threats such as Salamence and ScarfChomp will rest knowing that
they can be switched out at a moment's notice to a check which
can keep the offensive momentum going. With a boosted priority and access to a psuedo-Protect that even softens up your physical counters,
late game cleaning just got easier.
Something more
niche? Capitalizing on the lack of power creep this gen, a
full defensive set could work wonders with any Dragon's carrying great bulk and/or spDef *cough*
GOODRA *cough*...
WallOfSwords@ Rocky Helmet/Lefties
Relaxed
252HP/252Def/4Atk
-King's Shield
-Toxic/Thunder
-Shadow Sneak
-Iron Head/ Sacred Sword
Working off of Goodra's pitiful physical
everything defense, Aegislash can even come in as a
basic utility: working either as
a status spreader or a
stall unit. Of course, this doesn't work just with the Goomeister: any Dragon will be
grateful for something to switch into to avoid Ice/Fairy/Rock/ moves for the standard dragons, aswell as Bug/Fighting on top for Hydreigon too.
Of course, these are all rather brief, but the emphasis must be placed on the compatibility of Dragon and Aegislash. The Dragon's may not have to worry about the Fairies just yet.
