One ruling from Wizards of the Coast
- 24 September 2021If an effect causes Vengeful Strangler to transform on the battlefield, rather than leaving it and returning transformed, then Strangling Grasp doesn't become attached to any object and is put into your graveyard. This won't cause abilities that trigger when a creature leaves the battlefield to trigger.
