What do levels do in the TCG?

Question

On some of my HG/SS generation Pokemon Cards I see that they have level Eg. Lvl. 6 Zubat or in the case of my little brother level 598 Nidoking! (O.O) (I am pretty sure it was a misprint). So what do they do?

Answer 1

Nothing. Although there are Lv X cards which can evolve from the basic form of the Pokemon.

I agree completely, other then one thing: The level of a pokemon card may affect how much damage they do. However, I couldn't find a specific example. XD

Wouldnt higher 'level' cards have more powerful moves?
