i dont know if this game is still being developed as most of the posts in the dev area are incredibly old. but in case it is.
this card is so bad that its just disappointing. all of the other shards give you powerful effects with little to no downside. but this one benefits your opponent almost more than yourself. you spend 1 or 2
to draw 3 cards for you both.
now i thought you could play around this by playing the card when your opponents hand is full and only you get the draw. but it turns out neither of you draw cards in that case. you always draw the same number of cards that your opponent physically draws. which makes this shard either no benefit to you over your opponent or just a waste of mana.
my proposal for a change:
sacrifice 1 creature to draw 2 cards. 3 if you have the
mark.
alternative:
sacrifice 1 creature. draw a number of cards equal to its health + 1 if you have the
mark
i think this fits well with the general
theme of burning your creatures for extra power.
