Gretchen Titchwillow Gretchen Titchwillow makes a fine mana sink
Filter cards using many different parameters to find exactly what you need for your deck
That means that if they can't make you a strong offer, they'll refer you to the stores that can so that you can make an informed decision, rather than trying to lowball you in hopes that you'll cave
That thickness matters: it resists flexing, prevents corner compression, and protects the factory shrink wrap from scuffs, dents, and pressure marks that permanently lower grading and resale value
