Regeneration Fails

[Harribel]

If multiple creatures die only one seems to get regenerate ability even though others have or have an artifact/land that regenerates target creature as well.

In this instance 2 Ancient Silverbacks and Raging Gorilla with Land Yavimaya Hollow, only first Ancient Silverback (that didn't die) was regenerated with no options available to regen other 2 that did die.


Thanks for all your hard work.
