My jimmies remain unrustled
Arena Trap Steelix: This one is pretty scary on paper, and would probably be just as scary in practice. Being abl. e to trap anything would be amazing, and with Curse + Rest, Steelix would very easily be able to set up on pretty much any physical attacker, as well as any defensive Pokemon not relying on Seismic Toss. Just one slip up, and you'll soon have a +6/+6 Mega Steelix ready to rip apart anything in its path on your hands. I'm almost scared to see this thing winning, as I'm typically wary of trapping Theorymons, but I don't think this would be too broken.
Normalize Regigigas: I'm mixed on this one. On one hand, you don't have to deal with Slow Start crippling your Attack and Speed, and you have access to a Normal-type Thunder Wave for crippling faster foes. On the other hand, having literally no coverage because of Normalize is pretty lame, and pretty much every Rock- and Steel-type can wall you. It's basically getting rid of one crippling ability and getting another crippling ability, but not as crippling. I dunno, I'm probably just biased, but I'm not really a fan of this one.
Tinted Lens Zygarde: I actually like this one. With Tinted Lens, it doesn't have to predict as often, as Steel-types no longer resist its Outrages and Extreme Speeds, thus making a sweep fairly easier to pull off. A Coil or Dragon Dance set would be pretty sweet with Tinted Lens, as not having much coverage isn't that much of an issue anymore. Not my favorite of the bunch, but I do like it.
Adaptability Galvantula: This one. I really like this one. Adaptability makes Galvantula a powerful attacker, and with Electric/Bug coverage being surprisingly good, it can actually be pretty easy to pull off a sweep. To put Adaptability Galvantula's power into perspective:
252 SpA Choice Specs Adaptability Galvantula Thunderbolt vs. 252 HP / 104+ SpD Mew: 198-234 (49 - 57.9%) -- 53.9% chance to 2HKO after Leftovers recovery
252 SpA Choice Specs Keldeo Hydro Pump vs. 252 HP / 104+ SpD Mew: 220-259 (54.4 - 64.1%) -- guaranteed 2HKO after Leftovers recovery
As you can see, Galvantula's Thunderbolt, a no-cost attack, is only slightly weaker than Keldeo's Hydro Pump, a low accuracy move, so Galvantula certainly has power going for it. And while not powered up, it also has some coverage in Giga Drain to slip past most Ground-types and to gain health. I personally see a Choice Scarf set working out for it fairly well, as it could use Volt Switch very effectively to maintain offensive momentum while still hitting very hard, and could be a big threat to sweepers. A Life Orb set would also be effective, being able to bust through walls while still being a threat to some offensive Pokemon. Now I know that 108 Speed isn't as significant as it used to be, but that's what Sticky Web is there for, as you can slow down your competition and plow through offensive teams. Plus, you kill most things that have access to Defog, such as Skarmory, Latios, and Mandibuzz, so you can lay down Sticky Web and keep it. All in all, my favorite of the bunch, and definitely getting my vote.
