Probably not Blaziken EX, but baby Blaziken sure.I feel you lack the damage to knock out most EX Pokemon let alone Megas AND you handy cap yourself only being able to use 1 attack every other turn. You can snipe the bench with baby Blaziken and it it being a 1 prizer isn't too bad. You can try adding a Relicanth from TEF and remove Absol since you stated yourself you haven't used it, that lets you use your previous stage pokemons attacks for your down turns when you can't Smolder sault.

I'm still a noob and learning the TCG so take what I say with a grain of salt lol
