Describe the Bug:
Nim Shambler has the usual bug:AI sacrificed Nim Shambler to regenerate same Nim Shambler.

Which card did behave improperly ?
Nim Shambler

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
Manalink 2016/01/15: Battle For Zendikar v2,duel

What exactly should be the correct behavior/interaction ?
Nim Shambler can't sacrifice itself to regenerate itself.

Are any other cards possibly affected by this bug ?
-

Fixed that it couldn't activate to regenerate at all in dev in commit 42f0b88e. The rest had already been fixed.
However it should really use a regeneration shield so it can sacrifice other artifacts or itself without being dealt lethal damage.
