Ugh. Lost my Triples streak, peaking at 119. The sad part was that I could have actually won the lost battle, had I bothered to put PPups on every move my Porygon2 knew...
Lost battle #120 here: WUWG-WWWW-WWW4-8UUE
(Don't watch until the end, it's just PP stall wars)
Yeah, that's a Porygon2 taking +6 Dragon Pulses from a Latias like they were simply a stiff breeze. I love Porygon2.
Anyway here's my team, which literally had no synergy at all. It was basically "choose a few favorite mons, try out a new mega, add in Terrakion just cuz." I'm surprised how well the team worked.
Serperior (Florina/F) @ Light Clay (Position: Left)
Ability: Overgrow
Nature: Timid
EVs: 252 HP/4 SpA/252 Spe
-Reflect
-Light Screen
-Taunt
-Giga Drain
My absolute favorite mon, and pretty much the backbone of the entire team. Its mission is to set up screens as fast as possible, Taunt anything that would be annoying like stallers or statusers, and Giga Drain until dead. I used to use Klefki as a Screener, and Prankster screens is always nice. However, Serperior had some advantages over Klefki, the main thing being Taunt, and the ability to sustain itself with Giga Drain. 113 Speed is enough to outspeed almost any non-Scarfed mon, so Prankster wasn't really necessary.
Terrakion (Might) @ Choice Scarf (Position: Center)
Ability: Justified
Nature: Jolly
EVs: 4 HP/252 Atk/252 Spe
-Rock Slide
-Earthquake
-Close Combat
-X-Scissor
This guy is so good. Main use was just to spam Rock Slide over and over, though in some cases I'd opt to use Close Combat or Earthquake. X-Scissor was for the Psychics or Grass types that threatened to do things early. Rock Slide flinch hax has saved me so many times as well. It used to have a Choice Band, but I found out that Speed was more valuable than Attack.
Charizard (Fury/M) @ Charizardite Y (Position: Right)
Ability: Blaze/Drought
Nature: Timid
EVs: 4 HP/252 SpA/252 Spe
-Fire Blast
-SolarBeam
-Focus Blast
-Fly (lol)
Special Nuke. This guy deals tons of damage to pretty much everything. The only problems with it are its poor accuracy moves (I considered using Flamethrower over Fire Blast, but Fire Blast is better at nuking neutral mons like Cradily or Gliscor), average speed (100 is not good enough) and the fact that any Rock move absolutely kills it even with screens up. Oh, and the fact it has Fly instead of something more useful, although Fly does attack across the field in Triples so it has helped sometimes. The danger in using this guy is that sometimes I forget the opponent is faster, or they have a scarf, and they OHKO my Zard with a Rock move before it can do anything. And, Drought works both ways. If the opponent has a lot of Fire types, Drought boosted Fire attacks will hurt even with screens up. Overall though, I like this guy more than Megazard X.
Latias (Dizzy/F) @ Leftovers
Ability: Levitate
Nature: Timid
EVs: 4 HP/252 SpA/252 Spe
-Dragon Pulse
-Psyshock
-Roost
-Healing Wish
All around special attacker. Can take hits, Roost them off or use Lefties recovery, and Dragon Pulse can hit across the field. Healing Wish is in case Terrakion or Megazard Y gets terribly hurt. Walled by Steels, though, which is annoying.
Porygon-2 (Hacker) @ Eviolite
Ability: Trace
Nature: Calm
EVs: 252 HP/32 Def/224 SpD
-Ice Beam
-Thunderbolt
-Recover
-Thunder Wave
THE TANK. This guy is the tankiest mon I have ever seen. I think he died only once throughout my whole streak, and it was because of a critical. Thunder Wave is useful to slow down fast threats, and BoltBeam coverage is great overall. Recover makes it so it can't die. I hate how Trace works in Triple battles though, sometimes. I've accidentally traced Traunt before, and I would have totally lost one battle had my Porygon-2, one of my last mons so no switching, Traced an opponent's Regigigas's Slow Start. Luckily, it Traced something else.
Porygon-Z (Error) @ Life Orb
Ability: Adaptability
Nature: Timid
EVs: 4 HP/252 SpA/252 Spe
-Tri Attack
-Dark Pulse
-Psyshock
-Nasty Plot
My secondary nuker in case Megazard Y goes down. Not much else to say about him, he barely got used unless I was getting hit hard. Useful to kill bulky mons, as after a Nasty Plot Tri Attack OHKOs everything that doesn't resist it. Also my second favorite mon, so that's probably why it's even used lol. I used to use Jellicent, but Drought interfered with Scald.
As you can see, almost no team synergy other than "put down screens, attack things." The main problems I had were speed issues. Terrakion is the fastest, but next is Serperior at 113 Speed, Latias at 110, Megazard at 100, Porygon-Z at 90, and Porygon-2 at 60. A lot of mons are faster than most of mine so I have to be very careful otherwise I can lose 1-2 mons quickly. Oh, and the fact that most of my team other than Terrakion are Special attackers, which can be a problem if facing Calm Mind users. Other than that, this team worked pretty well.
I dunno how to improve it, but man I do not look forward to trying again. I want to get to 200 wins though...
