As far as I am aware the most recent release fixed the "resolve all + new adventure spell bug". I'll ask around about this issue; neither of these actually has to do with the rules engine, so I don't have much use in fixing them. #wotc_staff

That's rules correct! The tuck ability on God-Eternals is a triggered ability - it can only fire after the creature has been successfully put into your graveyard or exile, which happens after your option to send it to the command zone. #wotc_staff

Thanks for the report, I have a fix coded up. #wotc_staff

I mean, I learned about like three bugs this weekend. Sometimes it's real! #wotc_staff

We're sorry to hear that you have encountered an issue. If you haven't had a chance to already, please be sure to submit a request at: https://mtgarena-support.wizards.com/hc/en-us/requests/new so our team can look into the issue ASAP. We'd be more than happy to help!

Would you please clarify what you mean by that? I just tested using God-Eternal Kefnet's ability to tuck back into your library and I was able to draw, play, and murder him back to the command zone as expected. Sorry Kefnet. #wotc_staff

No, the underlying code is basically "matching" on a situation in the game. Whenever we have one of these "other than" situations, it has to find the object that this noun is other than, in order to ensure they are not the same object. #wotc_staff

Almost certainly an anaphora resolution issue, where "another" is interpreted to mean "other than the one you returned" - if you returned nothing, then it can't match any objects as candidates for returning to your hand. Pretty interesting problem... Most of us are going on vacation soon, so it might not be fixed for January sadly. #wotc_staff
