Couple quick points of advice from me:
1. If you square up the deck and look at all the cards together, it DOES look a bit blotchy. I put on 3 layers and nothing changed so just beware it won't look perfect.
2. Be very very careful and don't rush it. I just slid the marker down all 4 sides and worried about the corners at the end. I made a couple mistakes and the sharpie dries literally instantaneously so I have a couple slightly messed up cards
3. Black looks amazing and not blotchy so that's the backup plan if you don't want to try a color.
Overall, I'm happy with it. It fans about the same, but also be careful because you handle EVERY CARD individually and you can put your oils on a card and mess up the fanning. I may have done that. But its a black tiger deck, no big deal if it comes out bad
