Eevee and Charizards are one of the best Combo's in my opinion! The best Strategy, is to get an Eevee out with a Charmander or 2 on the bench, for starters you should attach an Energy to Eevee, and Tail Wag, then Pray it Works!!!! Then next turn, attach an Energy to charmander, and Tail Wag, next turn its best to attach one last Energy and attack using Quick Attack, and use Tail Wag a few times, in case of emergency... also while you are attacking with Eevee, don't forget to power up charmander! And one main mistake that most people make, sending out their Charmander before its powered up to max, and they don't have to, if your going to send it out, make sure you have the Charmander powered up to max... then send him out, ONLY SEND HIM OUT IF YOU HAVE TO! After that begin evolution to Charmeleon, at this rate Eevee is practically dead or is dead, try to send out another or, begin using more tail wags then attacks! After a while of this your opponent should frustrated and mad... get charizard out there on strong guys, (or if your on the last prize!)And_____ well, you get the point! ;-)
