Ok so heres 2 Major suggestions and a few minor ones.

Major:
1.Rework the whole design of the shadowera.com website. Looks too dull/old and dark.
2.Expansion with the rework of the whole site.
Minor:
1. In the game the background should be a lighter background not a dark one, because the cards kinda blends in with the background and makes the game look dull.
2. Change App Store Shadow Era Icon make a new one add new description etc and show the new expansion in the pictures.
All these should be done in one major update.
