Here's my battle

Pidgeotto (Middle, Normal/Flying) vs Clefable (Final, Fairy) No type Bonuses. Clefable wins based on Evolution stage.

Sandshrew (Basic, Ground) vs Ivysaur (Middle, Grass/Poison) Sandshrew's ground is super effective and Ivysaur's grass is super effective, therefore they cancel each other out. Ivysaur wins based on Evolution stage

Metapod (Middle, Bug) vs Charmander (Basic, Fire) Charmander's fire is super effective. Based on Metapod's evolution stage, it is a draw.

I win 2 of the 3 battles. (so close)
