So, I actually wanted to try out the new graveyard gem mechanic, even though I think it's rather cumbersome to setup. I used Underrealm Lich to dump cards in my yard (also to fulfil the graveyard objective). However, it seems that cards that should create graveyard gems when hitting the graveyard FROM ANYWHERE do NOT create graveyard gems. In my case the green Aracnir uncommon spider (Chainweb Aracnir I believe is its name). When I was finally able to Escape it, it ALSO didn't get the escape buff. Great mechanic!
@Oktagon_Support : is there anything I missed about how graveyard gems and the Escape mechanic work or is this another bug??
