- 13 July 2018If Palladia-Mors leaves the battlefield and returns, it's considered a new object, even if it's represented by the same card. It has hexproof again until it deals damage.
- 13 July 2018If a triggered ability triggers at the same time that Paladia-Mors deals damage for the first time, targets are chosen for that ability after Palladia-Mors no longer has hexproof.
