I‘m not yet fully satisfied with the card movement, too. Do you think the card disappearing effect was a step in the right direction?
EDIT: originally wrote a comment that mischaracterized the animations, rewrote it.
The feeling as the cards fly into the enemy before going to the discard feels good.
The way they get drawn and discarded feels good.
The “phantom card” in the hand that dissolves while the real card moves feels wrong, compared to many other games I’ve played with hands of cards. The fact that it’s a distinct object, while the card itself flies off, feels off compared to everything being based of the card itself.
