Discard now takes your first copy of a particular card instead of the last? This seems extra punitive. And still no fix for the horrible search UI, cards still don’t work (Thanks for nothing Karn), mechanics are still hit or miss (stealing hasty creatures), unbalanced events, and reduced rewards. I wish they’d spend some effort fixing the game a bit, before making it more difficult to advance without spending tons of money on cards that most likely won’t work as advertised.
Can you tell us which card you are talking about? Rotting Regisaur specifies “first card”. Rowdy Crew used to discard the first card although it isn’t specified. Infinite Obliteration discards first and last card. If you feel it’s a bug about a specific card you should post it in the bug forum.
Grafdigger’s Cage will discard your first card in some instances. Karn gets tagged using his first ability. Every update brings back or creates little bugs throughout the game.
Grafdigger’s Cage forces a discard when you fetch a card. It shouldn’t discard the first card though.
