Skarb Tips

Calculate expected value – Arcana drop rate is low
Set a budget – Chasing Arcana can be expensive
Consider direct purchase – Arcana on market may be cheaper
Sell duplicates – Offset costs with tradeable sets

Market Impact

Cosmic Hoard affected Earthshaker Arcana prices:

Cena drop – Increased supply reduced exclusivity
Still valuable – Arcanas maintain baseline value
Opening cost – Still expensive to obtain through treasure
Market purchase – Often more economical than opening

Collecting Cosmic Sets

For non-Arcana collectors:

Complete sets offer great value
Space theme is cohesive
Luna and Tinker sets particularly popular
Cenas typically stabilize 2-3 weeks post-release
