Dragalge Bulky Offense:
I built a team around Choice Specs Dragalge with the moves Draco Meteor, Sludge Wave, Hidden Power [Fire] and Focus Blast.
The Teammates are Choice Scarf Gardevoir, which can take on faster Dragons like Noivern, Trick to lock annoying Pokemon such as Registeel and Cresselia into one Attack and making them less useful.
Last slot here is Healing Wish to give one of the Pokemon a second go on the field.
Chesnaught is there for Spike stacking and allow Dragalge to weaken it's foes. Synthesis and Drain Punch with it's Leftovers for longevity.
Mega Blastoise here is the bulky Water Type in this Team, I gave it Scald cause you can burn possible switchins and Rapid Spin as the Hazard Removal.
Dark Pulse is to take on Pokemon such as Cresselia and Bronzong, to hit them super effectively.
Escavalier takes on opposing Gardevoir with its strong STAB iron Head, which is also able to Pursuit Trap it. Drill Run as Coverage Option and Megahorn as another strong STAB.
Rhyperior sets up Rocks and is a check to Entei, Moltres, Tyrantrum and Diancie and Ice Punch is to catch Gligar via switchin.
