I reported on this issue a month ago, and, despite several updates, the issue still persists (along with a slew of others).

I just played a Timeless game and cast Black Lotus and got the achievement. Apparently, you need to play a game against someone other than Sparky to get this achievement.

Good luck all!

I had the same issue. Today I used Time Walk in a Brawl match and got the achievement.

I posted a few days ago, and am still having the same issue: I play multiple cards in the Power Nine, and still don't get the achievement.

I did read a post on another discussion board that stated that for them the bug HAD BEEN FIXED with the patch that rolled out on February 18: has anyone else had their issue resolved, or are there still those of us having the same problem? :-)

Same for me

+1 to this issue. In one game I cast mox jet, and in the second black lotus. Neither game unlocked the achievement.

Same issue, tried five times in five different matches

Built a deck to get achievement specifically... tried it both against Sparky and live BO1 match. Cast Black Lotus both times... no achievement awarded.

Same issue, used Oracle and cast Time Walk and a Mox from hand and Ancestral and Lotus from the top of my library. Got the Cast 6 spells in a single turn achievement from the game but not the Power 9 one.

I am having this same bug. Cast a Mox Ruby off of a Ruby Collector - it did not register.
I also cast Time Twister off of Oracle of the Alpha - and that play also did not get me the achievement.
PC on Windows 11.

Casted almost all of them Time walk, Black Lotus, Mox -s

This happened to me also, and I tried twice. Both times using Android phone. Second time was Mox Jet (see screenshots), I didn't pay attention to the first time.

Also happened to me, casted time walk and time twister in same game
