Though not a common choice in RU, Gurdurr's typing, ability, and Eviolite-boosted bulk make it the perfect counter for this team. Gurdurr's Sheer Force allows it to deal out a powerful Ice and Fire Punch, useful for taking down the likes of Druddigon and Accelgor respectively. Due to its typing resisting both of their STAB moves, Absol and Accelgor will have to rely on Superpower and Focus Blast, both of which do ~50% at most to Gurdurr, and, thanks to its buddy Eviolite, it can take even an Outrage from Druddigon with no problems. And Bulk Up. Arceus help you if this thing gets to Bulk Up. Its impressive bulk (obviously) becomes monstrous, and it can deal out extremely powerful punches that can OHKO even Drudd.
As for teamwork, this guy was practically made for Slowking. Its typing lets it take on the Dark and Bug moves that would end Slowking, and its monstrous Defense works well with Slowking's impressive Special D. And let's not forget about that Trick Room, allowing Gurdurr to outspeed the other team entirely while dealing its massive damage. It also works well with Escavalier because it forces Druddigon into an Outrage, allowing for a safe switch in, and it hits those that Bug/Steel/Normal can't cover for super effective (Magneton, Durant, etc.).
In short, this little guy can take mighty blows and more than return the favor, and is a great friend to have.
