Shadows and other consumables have been on the rise recently. People have rinsed their clubs of the ones they had on recent guaranteed TOTS packs and TOTS WL rewards. I think they will continue to rise more with La Liga guaranteed TOTS packs today and La Liga TOTS WL rewards tomorrow.
Shadows: PS4 2k XBOX 3k PC 3k
Look to sell on Friday, May 14th before the BuLi TOTS pack openings. A profit of 1-2k would be solid.
