I thought it was a great idea to buid a Rain team with Tortnadus-T. So, I started building it with Tornadus and then I add the rain core Pelipper+Kingdra. Th next pokemon I chose was MScizor, because it helps a lot with Gross and in rain it's a very good pokemon. Landorus is the next I selected because it gave me a lot of things, specially rocks and physically offensive pressure. And the glue of the team was Tangrowth. Tangrowth helps a lot with special pokemons and I chose it because it's a sponge of hits.
Pelipper has those EVs in speed to outspeed defensive Lando and Defog because I have Hurricane on Torna. Tornadus is LO because, in my opinion, in rain LO>AV and it runs superpower instead of Heat Wave due to Superpower defeat TTar that change the rain and Heat Wave is less effective in rain. Lando is rockium to deal better with Celesteela, Zapdos or Rotom-W.
