Wow thanks, you really looked at it deeply and took time to think about the mechanics 👍
Totally agree the flow is a bit rough. I like your idea of a "grope" card to make the beginning phase more engaging. I hope I'll manage to add that and upload it today.
In general, I think the game would benefit from having more focus on the deck building, e.g. by allowing the player to choose at least parts of the starting deck (and maybe allow some fine tuning between rounds) instead of making it fixed. But I'll have to see when/if I get around to that.
