Let's breathe some life into this section! Metalynx Discussion

[Dragonstrike]

Really interesting data! At least to me, it demonstrates how threathening the green cat can be. I'm actually surprised to see that even those mons that resist his moves (be it 2x or 4x) still have to fear switch in. With just 3 moves, Mega Metalynx have enough coverage to deal with everything and even his own counters, although you'd have to rely in some predicts to do it. But still, that mon is insanely strong. He applies so much pressure in the opponent to a point that your enemy has to think a lot and outsmart you everytime. Just one mistake when switching in a mon and you might be dead. 

Yeah, gotta be careful if you're switching into an offensive M-Metalynx.  140 Atk is a LOT.  Switch in on the right moves though, and Metalynx is gonna take a huge chunk of damage.  Chimaconda only fears EQ, for example.  Beliaddon is such a beast, it only partially fears EQ, with or without Intimidate.  Seikamater doesn't care about anything except a Meteor Mash.

Poor Firoke and Pajay get the short end of the stick since they're 4x weak to Rock. All the other 4x resists can switch in on those resistances just fine. Stealth Rock really ruins the fire bird/bug's day.

Let's also keep in mind that only one of these pokemon I just listed was fully invested in Physical Defense, though.  Metalynx is going to have a hard time against dedicated physical walls that can hit back if it doesn't have a Swords Dance up.  Or itself.

VS Offensive M-Metalynx: 252+ Atk M-Metalynx Earthquake vs. 0 HP / 4 Def M-Metalynx: 84-99 (27 - 31.8%) -- 1.4% chance to 3HKO after Stealth Rock

VS Physical Tank M-Metalynx: 252+ Atk M-Metalynx Earthquake vs. 248 HP / 8 Def M-Metalynx: 84-99 (22.5 - 26.5%) -- 96.4% chance to 4HKO after Stealth Rock

Metalynx is also not super fast, so that's the other thing to keep in mind.
