Anya, Merciless Angel

Damage dealt to Anya is tracked even if Anya has indestructible. For example, if Anya is dealt what would be lethal damage and Anya loses indestructible (perhaps because each opponent's life total is too high), 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.

If damage is dealt to Anya and to your opponents at the same time, Anya may gain indestructible and/or extra toughness before state-based actions are checked. Similarly, if damage is dealt to Anya by a source with lifelink controlled by an opponent, Anya may lose indestructible and/or toughness before state-based actions are checked.

If a player's starting life total is odd (Commander Vanguard? Sweet.), half that player's life total will be a fraction, and that's okay. For example, if an opponent's starting life total is 41, half that number is 20 ½. If that player's life total is 20 or less, Anya will have indestructible.
