It's a whole market Supply & Demand situation.

Not requiring CP means that there are more cards than are currently needed.

This results in Supply > Demand.

However, initiatives, such as Land will sink some cards away from the Market.

The benefit is the pricing allows for everybody to access the game.
The downside is that Botters can maintain accounts for cheap. The upside for Botters is they accummulate rewards, such as Soulbound Cards, that may become lucrative in the future.

It is a tumultuous time. It is an exciting time.
