Official rulings
The 8 most recent official rulings for Invasion of Xerex // Vertex Paladin, newest first.
- 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.
- Sieges each have an intrinsic triggered ability. That ability is "When the last defense counter is removed from this permanent, exile it, then you may cast it transformed without paying its mana cost."
- A battle can be attacked by all players other than its protector. Notably, this means a Siege's controller can attack it.
- 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."
- If a Siege never had defense counters on it (perhaps because a permanent became a copy of one), it can't have its last defense counter removed. It will be put into its owner's graveyard. You won't exile it or cast the other face.
- If a battle has no defense counters, and it isn't the source of a triggered ability that has triggered but not yet left the stack, that battle is put into its owner's graveyard. This is a state-based action. This doesn't cause a Siege's intrinsic triggered ability to trigger.
- 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.
