As far as checking this core goes, Rotom-W does an ok job. It's able to switch into Scizor's attacks relatively easily, taking 30% max from U-Turn, and burn it, forcing it out and crippling it for the rest of the match. Terrakion is trickier, as Rotom-W is not going to like taking a STAB move from it. It can, however, force Terrakion out in a 1v1 scenario, threatening a potential OHKO with Hydro Pump after Stealth Rock or a crippling burn.
As a teammate, Rotom-W helps out with a few different things. It's access to Volt Switch means that between it and Scizor, Terrakion will have plenty of opportunities to come in and punch holes. It's typing gives it some nice defensive prowess, giving the core a check to Talonflame and Heatran, while also providing a secondary check to Jirachi and Mega Metagross. Scizor and Rotom-W have a lot of great synergy together, as Scizor is able to Pursuit trap or set up on counters like Latios, Celebi, and Amoongus (Spore sucks). Rotom-W's ability to spread burns makes it really annoying and allows it to wear out the opposing team through constant Volt Switches, U-Turns, and status damage. Speaking of status, Thunder Wave is really nice to support Terrakion, who can outrun would-be checks like Latios.
