Collectible Card Game Headquarters

Jace the Mind Sculptor's brainstorm (+0) ability works fine except when i try to put any planeswalker on top it says "invalid card type" (or "invalid target") (just as if I was trying to target an enchantment with a Doom Blade). I can put any other cards on top just fine.

Oh, I see, it's a global bug related to the changes we made in the targeting function for avoiding AI using Disenchant on Planeswalkers. It's fixed as 16d1128
