[fixed]Wail of the Nim etwine no regen 1 damage it cause

[Aswan jaguar]

Describe the Bug:
I have a Dross Prowler and a Myr Retriever if I cast Wail of the Nim with etwine so both effects take place either at regeneration step (if one has been also dealt lethal damage from another source) or at any other time both my creatures will die by the 1 damage.

Which card did behave improperly ?
Wail of the Nim

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 ?
Wail of the Nim because it creates a regeneration shield it regenerates the 1 damage it inflicts.
I don't know for sure if it regenerates both normal combat damage if the creature is blocked/dealt lethal damage then play Wail of the Nim with etwine will then also regenerate the 1 damage from itself or only the one from combat damage?

Are any other cards possibly affected by this bug ?

But are we implementing regeneration shields now? I thought it was decided to keep the original implementation of regeneration.

For this card it totally mess the etwine option if no shield.However Devs may want to just change the order of the 2 abilities first deal 1 damage then regenerate so that the card works more as it was made to work but we do have cards like Boon of Erebos,Necrobite, Butcher's Glee that create a regeneration shield legacy.

Those three and Unnatural Endurance use (through the vanilla_pump() frontend) regenerate_or_shield(), which is actually pretty flexible; they can be cast either during the regeneration step to regenerate normally for Manalink, or any other time to create a shield. How well the AI deals with that, or not, I haven't had time to really investigate.

I tested a bit and AI uses these cards both before and during the regeneration step knowing the creatures will regenerate.It doesn't seem to make AI worse -dealing with regeneration- than AI's normally behaviour.AI manages though defend/regeneration part a bit better than attack/regenerate.

Code redone in 301f15b following your suggestions

[Aswan jaguar]

Now in dev 778ccb5 version: Wail of the Nim when it resolves it doesn't make 1 damage nor regenerates your creatures no matter if you do it beforehand or when Manalink regeneration effects trigger. Same bug on all 3 options to cast it.

Fixed the no effect in resolution in commit 8a3bd62a.
