So at first i was not sure what to make of this but now I think it can be a valid alternative to Plascrete Carapace that has some limited use outside of meat damage matchups. You can use it to store cards for later use on it and it also works against a Ronin or other net damage kill combos that need more than one click to pull of. The backside is that you still lose the cards and you do not want to many cards on it since you get them all at once.
All in all I will at least try it out as a plascrete alternative that lets you get rid of useless cards without trashing them.
