#4 Spectacular Spider-Man (Black) Art Card (Gold-Stamped Planeswalker Symbol) Set: Art Series: Marvels Spider-Man Printing: Normal Increase: +$38.03 Current Market Price: $67.35 If words were money then this thing would be even more expensive due to the title it holds
If youd prefer to try an angle with red and green that doesnt revolve around mana ramp, Chishiro, the Shattered Blade does a very good job of rewarding use of Aura and Equipment cards

Other high-value cards include Basic Darkness Energy ($72.83) and Duskull ($65.19)
