Quote from: Necrologia
Being able to see through a card doesn't prove that a card is fake/real. The idea is to see how blotchy it is. Put a powerful enough light behind a real magic card and you can see through it. Real cards are a uniform texture. Rebacks will look much different due to the sanding and regluing process.
The idea is that you're supposed to see through a real card. You have to benchmark it with a real card to see if the same amount of ligh shines through.
