Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Teams are allowed one Ubers tier 'God' Pokémon. The other teammates receive the base stat of the Uber Pokémon corresponding to their position on the team.
Moves that deal direct damage to an opponent will 'pass' any hazard, status/volatile effects and stat debuffs currently on your side or Pokémon to your opponent's.
