Shard of capriciousness maybe?
Possibly, I don't know might change it later.
Hmm, a Shard of weapon?Think of a actual weapon lol.
Also, your card says that damage is doubled with entropy mark, but the notes don't say this.
It should be 2-4-6 damage if you have entropy mark.
Yes, that is what the damage would be, but my brain is not really working right now so I made a mistake.
Wouldn't be better that if your mark is chaos. it strikes twice?
also, why a shard is hitting the opponent?
Entropy IS chaos, the pure randomness of everything in entropy is so chaotic, that Entropy players have to be ready for anything THEIR cards might do.
As for a shard hitting your opponent. There are already a few shards that damage your opponent, this may not be the best example but Shard of the Void decreases your opponent's MAX health every turn. Also you can think about stabbing someone with a pointy object, like a shard.
