Seems like I underestimated, Chandelure - It can be quite dastardly with proper support. Its immunity to not only Fire- but also Fighting- moves can make it quite a bitch to handle. It's among the best user of Sub + Protect moveset, imo, since a Chandelure with Substitute cannot be shot down by super effective Sucker Punches. Not to mention Chandelure behind a Sub is one of the scariest thing to face x0 It's biggest pro is how it manhandles Cresselia. It's not particularly bothered by Cresselia's weak Ice Beam / Icy Wind or even STAB Psyshock, whereas Ghost Gem Shadow Ball 2HKOs all but the most specially-defensive Cresselia, and through Sitrus Berry, too. Good partners for Chandelure would obviously be mons that can quickly dispatch Heatran. Sheer Force Landorus and Hitmontop are particularly great for this. EQ users like Garchomp are actually less optimal for the task, since it would kill Chandelure in the process - Landorus and Hitmontop can focus-fire their STAB solely on Heatran with 0 repercussion to its ghastly partner. I've even seen HP Ground Lati@s used for such purposes. Hitmontop is particularly a useful partner, since it can block EQ and Rock Slide with Wide Guard and even allow Chandelure to OHKO most Cresselia with Helping Hand support combined with Ghost Gem-boosted Shadow Ball! After seeing the wrath of Chandelure, I will never underestimate it again ;x It certainly holds some advantages over Heatran by virtue of its Ghost-typing.
