Shallow graves, Rare, 14 bricks
Undead. Durable.
Wall +10.
If last card was discarded, gain 1/3 of its casting cost (max 10 of each).
Just wanted to say that I like this. Using bricks to fund other expensive cards would be very useful in an Undead deck, especially with the keyword gaining tokens. It could be useful in other decks with mixed gem/recruit cost cards as well. I wonder if taking two turns to discard and then gain +10 wall and variable resources is worth it for a Rare, however. For its cost and the necessary two turns, it could maybe stand to give twice the wall gain. Otherwise, let it work after a played card and maybe limit it a little more and only function if not New?
I will add that I don't end up with excess bricks in my Undead deck, so it's not like you can count on using it right away when drawn. Perhaps in other keyword decks, but not Undead.
