Official rulings
The 8 most recent official rulings for Invasion of Theros // Ephara, Ever-Sheltering, newest first.
If a token or a card that isn’t represented by a transforming double-faced card becomes a copy of a Siege, it can’t be cast as its triggered ability resolves. It will remain in exile. If it’s a token, it will cease to exist the next time state-based actions are performed.
If a permanent that is represented by a transforming double-faced card becomes a copy of a Siege, it will be exiled as that Siege’s triggered ability resolves, then it will be cast transformed. Note that this applies only to transforming double-faced cards, not to modal double-faced cards that can normally be played using either face.
If a battle that’s being attacked somehow stops being a battle, it is removed from combat. Similarly, if its controller changes in the middle of combat, it is removed from combat.
As a Siege enters the battlefield, its controller chooses an opponent to be its protector.
A battle can be dealt damage and be target of spells and/or abilities that target “any target.”
Damage dealt to Ephara is tracked even if Ephara has indestructible. For example, if Ephara is dealt what would be lethal damage and later loses indestructible (perhaps because you lose control of some enchantments), it will be destroyed the next time state-based actions are performed. However, the check for whether a creature dealt damage by a source with deathtouch is destroyed happens only the first time that state-based actions are performed after that damage-dealing event.
In a multiplayer game, if the protector of a battle leaves the game and that battle is not currently being attacked, its controller chooses a new protector for it as a state-based action. If it is being attacked, its controller chooses a new protector for it once no creatures are attacking it. This means that it continues to be attacked and can be dealt combat damage as normal.
Battles can’t attack or block, even if one also becomes a creature. If an attacking or blocking creature somehow becomes a battle in addition to being a creature, it is removed from combat.
