Since artifact piles are not shared, and it refers to Holder (which I don't believe transfers), I think technically you are correct that your teammate could rescue.  They are not restricted at all by the card, unless there is another rule or ruling that changes that.

However, I believe this would also mean that your opponents could still attack, and you would be restricted from blocking.

Although you are correct that the person to your left has the first option to block, technically you are attacking the opposing team as a whole.  Therefore even if the person to your left has Burial Shroud active, you could still attack their team.  However that player would be prevented from blocking.

Conclusion: Don't play Burial Shroud in TEAMS

So how does it stop you from blocking if you have shroud up?

Because if that player chose to block, then they would personally be being attacked.  And Burial Shroud doesn't allow that.

Burial Shroud targets a "player" not a location. 

I understand that it is a confusing card with regard to TEAMS, but this has been the way that Burial Shroud has been ruled for the last 5 years.  That's not to say that the status quo can't change.  However it would have to be a really compelling argument as opposed to just having a different perspective that "could" also be a valid way of looking at it.

just curious from a logical point of view

I applaud both curiosity and logic

P.S.  I'm looking forward to seeing you in a few weeks at EC Regs
