My team:

Lita the Pikachu (Basic, Electric)
Mizu the Squirtle (Basic, Water)
Trista the Abra (Basic, Psychic)


Lita the Pikachu vs. Pidgeotto (Middle, Normal/Flying type)--Lita puts in a heroic effort since Electric is super effective against Flying, but the match ends in a tie
Mizu the Squirtle vs Sandshrew (Basic, Ground type) Not a problem for a Water type--Mizu wins
Trista the Abra vs. Metapod (Middle, Bug type) Since Bug is super effective against Psychic, all Trista can do is warp away.

Result: Draw

(I think I did this right?)
