Shim’zar rotates this month. No one is going to spend spirit on crafting cards which will only last a few weeks. But there are fun cards from that set, it’d be great to see some them get one last hurrah.
How about discounting the spirit cost for Shimzar cards so that players can craft them at half-price? That would entice more people to meme lightning blitz, and also reduce the outstanding spirit balance so they buy more when the next expansion is released.
