What a weird form to give Ditto.
HP: 60, staying put for a while.
Duplicate: Good if you got the Dittos for it. If only Fossil Ditto was in use anymore, oh well. Still good in a pinch if you want to keep a specific Ditto alive.
Smash Turn: A bit costly but good side effect for a pinch and some damage to boot.
Retreat Cost: One, normal.
Energy Cost: Good for a water deck to get the real effect.
A nice ish pinch Pokemon overall, 7/10.
