Rulings

• 2020-06-23: A planeswalker with indestructible still loses loyalty counters as it's dealt damage and will still be put into its owner's graveyard if its loyalty reaches 0.
• 2020-06-23: The set of permanents affected by Heroic Intervention is determined as the spell resolves. Permanents you begin to control later in the turn won't gain hexproof and indestructible.
• 2023-07-28: A battle with indestructible still loses defense counters as it's dealt damage. If it's a Siege, it will still be exiled when the last defense counter is removed from it, and its controller may still cast it transformed without paying its mana cost.
