So I’m using her with Garruk’s tokens and after death her buff still remains on his tokens. I haven’t tested with non-token creatures yet, but just throwing this out there.
The buff lasting on other creatures after she dies was never a bug.
The bugs were:
- buff not staking properly. Old and fixed recently.
- her buff getting reapplied if the creature is resurrected(mostly green warden of murasa). This should have been fixed by yesterday’s patch.
Did not have the chance to test. - her activate skill not activable anymore upon resurrection. This is most likely still around.
took me a while to understand what the bug was as well. the bug isnt the creatures still having the buffs after she dies, thats a permanent effect of her skill.
the bug that occurred was, for example, having a murasa, dwynen and a skysnare spider on the board. you activate her abilty and skysnare spider becomes 8/8. He then blocks a creature and is killed, comes back to the battlefield thanks to murasas ability, but comes back as an 8/8 not a 6/6 retaining the buff from dwynen which was the bug. i think 
If that is what he means the patch notes reporter explicitly that I was fixed.
Again if that’s the case may be it is still bugged for tokens?(though I have to admit token should not even come back to life but… That’s paper magic).
I misunderstood the patch notes. I thought that they didn’t intend her buffs to last after SHE died.
Since her paper MTG card is more of an aura and not giving out permanent +1/+1 counters I thought they were trying to copy this effect.
