So... What is the point of attaching energy to him with Spiral Growth beyond just getting two more energy for that attack you'll normally only want to use once?
And a Gyarados without Fighting resistance?
4/10. He really lacks synergy with himself (does that sound right?) and his second attack should be renamed Russian Roulette. It'll kill you unless you're down to one prize or have some trainer card to extend your deck on the ready.
Edit: And just noticed how old this card rate is...
