Cant play Historic without rebalanced Alchemy cards? -> Won't play MTGA since I only played Historic.
Additionally, creating randomly generated cards never was a good idea in any digital TCG.

How about making changes the players actually want, like actual multiplayer? I guess whales are more profitable than salmon...

Suggestion1: Delete alchemy and refund,lol. Or make it Alchemy/Standard/Historic. With historic being "non-rotating", like you told your lies ;-).

Suggestion 2: Make less product, but review it before release.
