I often fail to give sufficient credit to Retaliate on heroes.

I spend so much time trying to come up with huge swings and recursive exploits that I think a slow and steady source of damage often gets lost in the mix.

Adamantium lacing not only provides that steady incremental damage, it also gives X-23 more HP and adds Piercing to her basic attack. And all for one resource!

I cannot tell you how awesome this is. But I am going to try anyway.

First of all, X-23 is designed, from the ground up, to rely on basic actions. While other heroes dodge and weave, X-23 attacks repeatedly and often. This makes piercing huge, as it ensures she deals damage directly to her target every time.

This is a great card. And I believe a simple 'tell' for this is that Endurance costs one and provides three hit points. Adamantium Lacing costs one, provides one less hit point and gives you Retaliate and Piercing. That is a textbook example of a hero card doing it better, which is exactly what makes me love this game.
