Good day RyanKoopa, I have completed your request!

The defensive value of the provided core is indubitably solid and it was fun for me to build a strategy around it since it was one of my GoTo defensive cores back in ORAS UU. However, since the team was half built already I had to make two minor adjustments to the original core during the teambuilding process to account for the team's weaknesses and strategy; I hope you don't mind.
Given the nature of the original three members I went with a balanced approach, and since Swampert, Sylveon and Crobat, the former two in particular, only have little offensive presence, the very first addition to the team that I singled out for the team was a win condition.
Bulky Swords Dance Scizor complements the team nicely with its Steel typing, relieving pressure from Swampert and Sylveon by aiding them with checking Mega Aerodactyl, Mega Altaria, SR Gliscor, and Latias amongst others. The set features
Toxic to pressure Stall builds (a playstyle that has been observed to experience a surge in usage lately), while preserving its ability to threaten offensive teams with SD and Bullet Punch. 136 Speed EVs outpace Adamant Azumarill, allowing Scizor to Roost off damage from Knock Off and Play Rough as well as picking off weakened BD variants with Bullet Punch. 96 Attack EVs with an Adamant nature always 2HKO max HP Mega Altaria (OHKO at +2). One obviously has to be careful around Magneton with this set since it forgoes the utility of U-turn and power of Fightinium-Z Superpower. Consequently, I adjusted the Crobat set to help the Scizor set in its endeavour to sweep. Crobat is a rather subpar Defogger in my opinion, much better suited to a full support set.
Taunt + Super Fang aims to weaken Steel types like Mega Aggron, Empoleon and opposing Scizor so that the team's very own Scizor may sweep. After some testing I decided to forgo Flynium-Z on this set for
Safety Goggles which makes Crobat the perfect counter to both Breloom and Amoonguss, both of which are incredibly annoying to deal with since they always force a sleep fodder. The next pick is nothing out of the ordinary but is still as effective as ever:
Choice Scarf Hydreigon patches up the team's speed tier and revenge killing ability, and offers a Ghost resist and an additional Ground immunity; it fits like a glove. At this point the team was looking awfully weak to any Azumarill set, even PerishTrap, and would appreciate an additional Bullet Punch resist.
Volcanion not only does the former two things, but also functions as the teams
Defog user and Gliscor lure with a
Shuca Berry equipped. I felt comfortably opting for a Defog variant here since Sylveon can keep Volcanion healthy quite well, the latter being able to switch in to Steel and Fire attacks as well as Choice Band boosted attacks from Azumarill aimed at the former.
You may have noticed that this team doesn't carry a Z-move and, frankly, I didn't feel the need to incorporate one. Flynium-Z is certainly a viable alternative to Safety Goggles on Crobat, although this does weaken the Breloom match-up significantly. Slapping a Z-move on Scizor may help to block Trick and absorb Knock Off, both of which are certainly helpful, but neither Steelium-Z nor Poisinium-Z has many useful applications in practice compared to the ubiquitous passive recovery from Leftovers. The lack of a Flying resist is certainly a weak spot of this team, especially with the increasing popularity of Mega Pidgeot, but is still manageable. To account for the trouble of switching in to Hurricane I changed the nature on Sylveon to Calm with minimal investment in Special Defense, a change that also helps when facing Life Orb Latias (which carry Psychic more often than Psyshock from my experience) and specially offensive Mega Altaria. Speaking of Sylveon, its ability to clear status ailments from Scizor and Crobat is integral to the team's success, especially when facing more defensively inclined teams. I attribute the lack of a dedicated breaker on this team to its nature of a balanced team. While Crobat fits this role somewhat (it is actually more of a disrupter than all-out breaker though) there is no designated "nuke button" on this team, which has to be kept in mind when utilizing this team. While the team does have its weaknesses, I have yet to lose with it.
I hope you have as much fun playing with the team as I had building it!
