OK this is all my opinion

I think dark charizard is better than the old one. first lets look at its
stats

evolves from dark charmeleon  80hp
1 colorless energy  nail flick   10 damage
2 fire continuous fireball  50x
flip a coin for each fire energy attached to dark charizard does 50 damage
times the number of heads discard one fire energy for each heads
weakness water  resistance fighting  retreat 3

this card is great. it can start doin damage for just one energy  and then do
100 damage for 2 fire energy (If your lucky)
here's an example on how its better than charizard, even though i like
charizard.

charizard vs. dark charizard
charizard attaches r energy 120 hp

dark charizard attaches r energy nail flick  80 hp

charizard attaches r energy   110hp

dark charizard attaches r energy  continuous fireball gets lucky and does 100
damage        80 hp

charizard attaches energy     10 hp

dark charizard attaches r energy nail flick    80 hp
dark charizard wins and isnt even scratched

of course, charizard has pros and cons.  here they are:

pros: attacks with just 1 energy
can do 100 damage for two r energies
highest hp in rocket
resistance to fighting

cons: 80 hp is only good for rockets
dark charmeleon
has to discard energies for big damage
