After a small gaming session with a few new folks tonight, we had a player intentionally turtle by not playing any cards and discarding their entire hand to restore 6 HP every turn.

So, in rules  v2025.03.29 I have changed the healing effectiveness from,

"you may discard any number of cards from your hand. Each card discarded this way restores 1 lost hit point."

to,

"Heal: You may discard up to 3 cards from your hand to restore 1 lost hit point each (up to 3 HP)."

For people that enjoy a more healing-centric battle, the healing variant also changed to,

"Potent Healing — You may discard up to 2 cards from your hand to restore 2 lost hit points each instead (up to 4 HP)."

I will continue to monitor healing effectiveness and make further adjustments as necessary.

I also made the rulebook in A4 size available for download.

Thank  you for your support!
