Hi! Thanks for your ideas.
- Regarding drawing and discarding cards: discarding gives 1 mana, while drawing costs 2. A player simply won’t be able to assemble a perfect hand—they won’t have enough mana. Moreover, cards also need to be played using that same mana.
- About healing during battle: we started with such a mechanic, but after testing, we had to remove it because it allowed players to fully heal during a battle with a weak enemy—just by defending against their attacks and constantly healing. Yes, it’s slow and tedious—but players usually choose the "efficient" path over the "fun" one.
