You're going to have plenty of try hards trying to convince everyone else that this is a bad, under powered card due to this that or the other card giving you a tough token or stunning the Villian at a better cost.

But this is always a fool's view. This works in conjunction with all of those things but as a separate layer, providing protection that ignores piercing, stalwart, and all those other things that bat other protections to the side and make them ineffective at times. And it allows you to still use those other layers, and even defend against weaker attacks, and can stay on the table until you need it.

Even in decks (or playing with other decks) that can provide cheap stuns and toughs, this is still a card you should be looking to get on the table, if and when you can, due to it being there on later turns when other damage prevention methods are being mitigated or not getting drawn into.
