Not really too sure why anyone would give this card anything higher than 6/10. Anything thats decent or semi playable should be 6-7, anything that you wouldnt think about is lower.
Maybe its just me but Im not seeing anything out of this card. First attack is pretty decent, 50 for 2 energies, but the key thing is that this guy is stage 2, meaning most of your deck would be dedicated to the Pokemon evolution line. If the stage 2 your dropping isnt going to really change the game, its not going to be worth all that effort to bring out.
Second attack is awful, 4 energies is not worth 80 damage and an energy discard is nothing that great, at least not in the long run. This guy cant really kill anything, he cant stack damage, I really dont see what uses it has since theres not very many possibilities with his abilities. In this meta this guy wouldnt match up against anything well or be able to really be effective against anything other than fire decks which other cards are already just as or more effective.
I give it a 5/10. Cant see myself ever running this guy. He has decent weakness and HP, retreat is good for Heavy Ball, but doesnt bring anything to the table other than a low cost 1 low damaging attack.
