Need the following in clan store or allow to buy for gold or place in chest bundles

OS Host expanders.  

All forms of combat boosters

Required build materials for gold purchase

Possible keys for gold

Precious dust for gold or clan store.

Maybe an auto help clansman clicker for clan if they purchase an item for a week.

Marching booster 75 in treasure boxes.

Actually, the treasure boxes need a whole rework to keep up with the challenges of the game.
