Thank you!

Good question :)

A new user will start with a wide range of cards for them to use and as they play & level up, they receive reward card packs. You are 100% correct that the trading aspect of this card game (which is huge, just like any CCG) is so incredibly expensive because of fees. It is impossible to purchase a card work $0.06 without paying much more than that card's value in network fees.

I personally have mostly stuck to purchasing the card packs and did plan out a bulk trading order in the past to keep the transaction fees as low as possible, but it is a huge problem.

They are rolling something called ImmutableX which they describe as a "high speed exchange." I don't know how it works on a technical level, but if you're interested you can read more about it here: https://blog.godsunchained.com/2020/05/08/introducing-immutable-x/

Thanks for reading :)
