Introduction
I started off with a core of Pelipper and Ludicolo, and then I added in Amoonguss as it appreciates the rain and counters trick room, which can turn tailwind and swift swim against me. I chose Mawile as my mega, as it provides intimidate and two useful STABs in fairy and steel, as well as ridiculously high attack. Landorus was then added due to a lack of raw speed, and to provide earthquake and rock slide. The last slot was a little contested, as I originally had Thundurus-T to provide more damage and an electric type STAB, but after getting destroyed by a Ferrothorn — I switched it to Marowak-Alola. After more experimentation, I found that I would be better with a little more bulk, and so I settled on Heatran.
Teambuilding Process
Ludicolo and Pelipper are the core of the team, as they have excellent synergy with drizzle and swift swim.

Landorus was then added due to a lack of raw speed in the rest of my team, and to provide earthquake and rock slide, which I was otherwise lacking. It also increases the general bulk of my team with intimidate.

The Team
Ludicolo @ Life Orb
Ability: Swift Swim
EVs: 108 HP / 252 SpA / 148 Spe
Modest Nature
- Scald
- Giga Drain
- Ice Beam
- Fake Out
Ludicolo and Pelipper go together and are my standard leads, as well as being the core of the team. Scald isn't Ludicolo's most powerful STAB (Hydro pump), but it is accurate and does a fair chunk of damage when combined with Life Orb and rain boost. Giga drain is Ludicolo's secondary STAB and provides a bit of health regen. It also shuts down opposing Gastrodon, which is a common answer to rain teams. Ice Beam is there for dragons and Landorus, which Ludicolo can outspeed with swift swim. Fake out allows me to shut down an opposing pokemon and gives Pelipper a chance to use Tailwind.Ludicolo @ Life Orb

Conclusion
I generally lead with Ludicolo and Pelipper and then bring along Mawile and whichever Pokemon has the best matchup out of the rest. If it looks like a trick room team, I tend to lead with Amoonguss and Mawile. If they have a lot of electric type Pokemon, I normally lead with Landorus and another Pokemon. I've found that my team can be a little weak to opposing Amoonguss, and it is also quite slow in general which is a problem if they also set up Tailwind, or prevent me from setting up mine. I appreciate any criticisms and suggestions you may have, and will read all of your comments.Ludicolo @ Life Orb
