Nice little card here. I'm surprised more people don't use this card. It has a very good combo with killing 70HP Pokemon. Also very good in a Venusaur deck.
Iron Grip and Guilotine
These two attacks can set up a very nice and harsh combo against your opponent. It works best if you got Venusaur on Bench but still is good by himself. You can use Iron Grip with 2 Grass for 20 and a chance to be paralyzed. Then, next turn slap on a Double Colorless Energy and Guilotine for 50! It is a very cool and effective combo.
Weaknesses
Pinsir does have some Weaknesses. Like not being able to attack first turn, no resistance, weakness to fire, 1 retreat cost and only has 60 HP. Now if he had a Haymaker stay 70HP you know people would be using him alot more
Rating
With the attacks and how good he is in a Venusaur deck, and the 60HP...I give him a 8.0. I think Pinsir is a very strong card.
