I want to like this card but am finding it tough to justify so far. What I like about it over electrostatic armor is you don't have to defend. However the issue is characters taking a "no defend" strategy that this card can enable are likely going to take damage pretty frequently. That makes the condition on this hard to meet. This in addition to the fact that it requires a lot of setup, either getting an HP upgrade in your hero deck or endurance or ideally both, to have a chance at keeping the condition active.
All in all it just fits ends up fitting more in an actual defense deck alongside electrostatic armor which is fine, but I wish it was more viable outside of that. Hopefully more cards enable it more in "no defense" in the future
