The new card changes are great. After maining AST for 4 years, having to play for balance (which is a real thing if you cared to optimize) was boring. Minor Arcana alleviated some of the issue but instead of throwing the card away, you just MA'd them away, to get something for it.

The current system is easier to balance and is more consistent at the same time, keeping the same RNG mechanics. If anything the new card system is harder to optimize and depth there is welcome over balance or bust.
