I just wanted to tell everyone about one of my favorite upcoming fossil 
cards.  It's Htimonlee:
HP: 60
Retreat Cost: 1
Weakness: Psychic
Attacks: 2 Fighting-Stretch Kick-Deals 20 damage to benched pokemon without 
applying weakness/resistance.  3 Fighting-Hi Jump Kick-50 Damage
What I am going to do now is compare Hitmonlee with Hitmonchan, another of my 
favorite fighting pokemon:
Hitmonchan:
HP: 70
Retreat Cost: 2
Weakness: Psychic
Attacks: 1 Fighting-Jab-20 Damage
             2 Fighting, 1 colorless-Special Punch-40 Damage
Now for comparing:
HP: Hitmonchan: Score Hitmonlee 0, Hitmonchan 1
Hitmonlee: 60
Hitmonchan: 70

Retreat Cost:  Hitmonlee: Score Hitmonlee 1, Hitmonchan 1
Hitmonlee: 1
Hitmonchan: 2

Attack 1: Hitmonchan: Score Hitmonlee 1, Hitmonchan 2
Hitmonlee: 20 to benched for 2 fighting
Hitmonchan: 20 for 1 fighting

Attack 2: Hitmonlee: Score Hitmonlees 2, Hitmonchan 2
Hitmonlee: 50 for 3 energy
Hitmonchan: 40 for 3 energy

So from this review I would say Hitmonlee and Hitmonchan are a tie.

Now here is a battle between 2 Hitmonchan and 2 Hitmonlee:

1st turn: Hitmonlee1-1 energy-60 HP-----Hitmonchan1-0 energy-70 HP

                                                        Hitmonchan2-0 energy

                                                        Hitmonchan2-0 energy 
10 HP
9th turn Hitmonlee 2: 3 energy 20 HP--You can either stretch kick to kill 
Hitmonchan                                  
                                                        2 or you can bring 
Hitmonchan 1 down to 10
                                                        HP with High Jump 
Kick.

So, as you can see, Hitmonchan and Hitmonlee are very much alike in different 
ways.  If Hitmonlee dealed the 20 damage straight to Hitmonchan then 
Hitmonlees definately would of one, but it is still a very good move because 
sometimes you need just one more prize, they have forward an extremely 
powerful pokemon, all you need to do is retreat for Hitmonlee and destroy a 
benched pokemon (there is usually one that is severely damaged but was 
retreated/switched to the bench, or sometimes just weak pokemon like abra or 
rattata or Voltorb or Magikarp.
