I have noticed Age of Acension decks being significantly cheaper than both COA and WC decks.

Are the age of acension decks not very good?

What is the reasoning behind this?

Age of Ascension has some odd anti-reap strategies which can make for long or unfun games. It has Legacy cards as the special gimmick, so if you like looking for those, go for it.

The places I go tend to have deck orphanages where players can donate or adopt wayward decks. If you can get decks on the cheap, pick em up and if you don't like them, maybe start up your own deck orphanage program.

It's commonly believed it's the weakest of the three sets, and Vault Tour results mostly confirm this. However, I have seen CotA even cheaper. I think cost is mostly a reflection of a set being older. Most players aren't concerned with which set is stronger but just want the new thing.

Thanks for the knowledge.
