Where to find pics with the same quality as the dotp13 ones?

I see the standard crops i find are not as good as the ones used in the game, and i want to make a deck with the same standard as the official ones.

You can't really find HQ pictures of any card you need, because illustrators don't always post them somewhere, so unless you are very lucky with the deck you are making, you are wishing something impossible.
The best you can do is to search on the site I suggested here.
