I'm having fun, but their login errors are making me considering bailing on the product altogether. This sort of thing is why I usually avoid early access

Hey man, just sayin you made a solid go of it and wanted to help pad your resume.

Taiga Kagami's review seems to be the most accurate.
WAIT UNTIL SEPTEMBER. That is the projected actual release.

You build lands across a map and use your deck of cards to do battle with the opposing player. Your mana can carry over from turn to turn so curving is not quite as important as in other card games.

The game is interesting, albeit slow (as demonstrated by their attempts at having widely viewed competitive tournies).
The barrier to entry is far below Duelyst but your ability to be competitive is crippled much more here. The meta shifts wildly with every patch so unlike Hearthtone for example, you can't still climb with the shell of a deck you had that was previously successful.

The balance is sketchy at best and quite inconsistent. I have two good examples of this.
When asked about a mind-control style card (Magda) the developers admitted that it was meant to have no place in competitive play, but once it found a super strong niche they eliminted the card altogether.
Then, in these patch notes below, they admitted to trying to make a card overpowered simply because they liked the idea of a "wild and exciting change".

I like the game, but it is not worth the ten bucks. Card crafting exchange rates are extremely unfavorable, but there is no cap to how much you can farm in a day which is nice.

Negative feedback is unwelcome in the discord server, as Taiga claimed. Unless you're part of the inner circle then they take everything you have to say without question.
Win trading is a thing that happens in competitive play without punishment (even in developer sponsored tournies).
