Teams
Pokemon Champions team archetypes
An archetype is a mechanic, not a vibe. Each of these is built around an ability that changes the battlefield and the Pokemon that profit from it. Every roster list here is queried from the game data, so it stays right through patches.
Rain
The engine is a Drizzle setter, and the payoff is Swift Swim sweepers moving at double speed. Thunder and Hurricane also stop missing while it is up.
Sun
Drought turns Chlorophyll Pokemon into double-speed threats, Solar Beam skips its charge turn, and Solar Power trades HP for a special attack boost.
Sandstorm
Sand Rush doubles speed under it, and the residual chip damage does the work a stall team needs.
Snow
Slush Rush doubles speed under it, Blizzard stops missing, and Aurora Veil becomes available. Champions sets this with Snowscape; Hail no longer exists.
Trick Room
The one archetype with no ability engine. You need a setter that survives long enough to use the move, and attackers slow enough to benefit from the inverted order.
How these lists are built
Setters are Pokemon whose ability creates the condition. Payoffs are Pokemon with an ability that only does something once the condition is up. Manual setters are everything that learns the move version, which is a much longer list and usually the wrong way to build the team, because you spend a turn and the effect runs out.
Nothing here is filtered by how good it is. That judgement is yours, and the power ranking is the closest this site gets to making it.
