How do Deathknell abilities on Equipment Gear or copied by Svellsongur work if equipment is only attached while the unit is in play, but Deathknell triggers after the unit dies and moves to trash?

Ruling: There is currently no official ruling on how Deathknell abilities interact with Equipment Gear or Svellsongur copying Deathknell abilities. This is a known rules gap awaiting clarification in version 1.2.

Nuances:

• The current rules don't support these interactions properly since equipment detaches when units leave play, but before Deathknell would trigger
• Temporary guidance is to play by "vibes" (assume it works as intended) until official ruling
• Potential solution being considered is adding a "marked for death" step during cleanup before moving to trash, allowing Deathknell to trigger while unit is still in play
• This issue also affects cards like Kog'Maw that reference unit stats in Deathknell effects
• Any rules change to fix this may have implications for other cards like Cruel Patron
