As long as this Pokemon is on your Bench, attacks used by your Marowak do 30 more damage to your opponent's Active Pokemon (before applying Weakness and Resistance).
Flip 2 coins. This attack does 10 damage for each heads.
I ordered 3 tins, and they made sure to send 3 different designs, thanks! Sadly 1 tin did arrive with a dent in it. It also took almost a week to be shipped.
